Auto merge of #6744 - matthiaskrgr:lintcheck, r=flip1995

more lintcheck updates

* do some refactoring and renaming here and there
* add comments to functions
* fix bug where git repos would not get checked out to the proper commits (cmd was not actually run in repo directory :sweat_smile: )
* print warnings if we can't clone or check out a git repo
* filter out noise from cargo-metadata errors and lint messages that contained absolute file paths (these would change with every pinned-nightly bump, polluting the logs)

changelog: more lintcheck refactoring and fixes for git crates
