staticcheck doesn't support 1.21: https://staticcheck.io/changes/2023.1/ , that's why the lint job is failing

This is quite ugly. Are there any news on when it would be supported? I kinda like the linting.

- name: Mark source directory as safe.
        run: git config --global --add safe.directory $GITHUB_WORKSPACE

adding this as a step after you checkout the code should solve this problem.

The error is:

-: error obtaining VCS status: exit status 128
	Use -buildvcs=false to disable VCS stamping. (compile)

Staticcheck 2023.1.4 included support for go 1.21 and latest points to 2023.1.6
