Add support of .NET `*Packages.props` files.

## Description
Add support of [Directory.Packages.props](https://learn.microsoft.com/en-us/nuget/consume-packages/central-package-management) files.
Also we can parse `Packages.props`  files. These files were used before `Directory.Packages.props` and use same format - https://github.com/aquasecurity/trivy/discussions/5379#discussioncomment-7316578
