I have a need to paste a large amount of text into a JSON string via the clipboard, but I hope it can automatically escape the clipboard content, which would be very convenient for pasting large amounts of text.

Here is a use case:

1. I want to set the github.copilot.chat.commitMessageGeneration.instructions setting

   {
     "github.copilot.chat.commitMessageGeneration.instructions": [
       {
         "text": ""
       }
     ]
   }

2. I have some text that I want to paste

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119](https://www.ietf.org/rfc/rfc2119.txt).
   
   1. Commits MUST be prefixed with a type, which consists of a noun, `feat`, `fix`, etc., followed by the OPTIONAL scope, OPTIONAL `!`, and REQUIRED terminal colon and space.
   2. The type `feat` MUST be used when a commit adds a new feature to your application or library.
   3. The type `fix` MUST be used when a commit represents a bug fix for your application.
   4. A scope MAY be provided after a type. A scope MUST consist of a noun describing a section of the codebase surrounded by parenthesis, e.g., `fix(parser):`
   5. A description MUST immediately follow the colon and space after the type/scope prefix. The description is a short summary of the code changes, e.g., *fix: array parsing issue when multiple spaces were contained in string*.
   6. A longer commit body MAY be provided after the short description, providing additional contextual information about the code changes. The body MUST begin one blank line after the description.
   7. A commit body is free-form and MAY consist of any number of newline separated paragraphs.
   8. One or more footers MAY be provided one blank line after the body. Each footer MUST consist of a word token, followed by either a `:<space>` or `<space>#` separator, followed by a string value (this is inspired by the [git trailer convention](https://git-scm.com/docs/git-interpret-trailers)).
   9. A footer's token MUST use `-` in place of whitespace characters, e.g., `Acked-by` (this helps differentiate the footer section from a multi-paragraph body). An exception is made for `BREAKING CHANGE`, which MAY also be used as a token.
   10. A footer's value MAY contain spaces and newlines, and parsing MUST terminate when the next valid footer token/separator pair is observed.
   11. Breaking changes MUST be indicated in the type/scope prefix of a commit, or as an entry in the footer.
   12. If included as a footer, a breaking change MUST consist of the uppercase text BREAKING CHANGE, followed by a colon, space, and description, e.g., *BREAKING CHANGE: environment variables now take precedence over config files*.
   13. If included in the type/scope prefix, breaking changes MUST be indicated by a `!` immediately before the `:`. If `!` is used, `BREAKING CHANGE:` MAY be omitted from the footer section, and the commit description SHALL be used to describe the breaking change.
   14. Types other than `feat` and `fix` MAY be used in your commit messages, e.g., *docs: update ref docs.*
   15. The units of information that make up Conventional Commits MUST NOT be treated as case sensitive by implementors, with the exception of BREAKING CHANGE which MUST be uppercase.
   16. BREAKING-CHANGE MUST be synonymous with BREAKING CHANGE, when used as a token in a footer.

3. I want to paste this text into the JSON settings, so I will move the keyboard cursor between "" and then press Ctrl + V to paste the text

   {
     "github.copilot.chat.commitMessageGeneration.instructions": [
       {
         "text": "|"
       }
     ]
   }

4. At this point, I hope VS Code can automatically recognize this paste action and automatically escape the pasted text, allowing me to directly paste the text into the JSON settings

   {
     "github.copilot.chat.commitMessageGeneration.instructions": [
       {
         "text": "The key words \"MUST\", ......"
       }
     ]
   }
