Raise minimum Swift version to 5.5 (#1483)

Motivation: Now that 5.7 has been released NIO is due to drop support for 5.4. gRPC Swift must do the same. Modifications: - Remove 5.4 from the CI - Add 5.7 release, move 5.7-nightly to main-nightly - Update Package.swift for the FuzzTesting subpackage to 5.7 - Update the README.md and Docc index page. Result: Minimum supported Swift version is 5.4
