chore(linux): Enhance GHA API check

This change adds additional checks for the symbols file:

- if a line with a method name gets changed, the package version number
  in that line also needs to be updated
- for major API changes (methods renamed or removed) the API version
  numbers needs to be incremented
- the API version numbers in the .symbols file and in `CORE_API_VERSION.md`
  need to match
