Improve error message for dubious git ownership

[alexef]

@timvink sorry, how did you fallback to builddate?

[timvink]

Sorry, should have been more clear. The error from this plugin is the first line:

ERROR    -  [git-revision-date-localized-plugin] Unable to read git logs of '/workspace/source-repo/docs'.  To ignore this error, set option 'fallback_to_build_date: true'

That's caused by this (too generic) bit of code:

mkdocs-git-revision-date-localized-plugin/mkdocs_git_revision_date_localized_plugin/util.py

Lines 148 to 155 in 6150fad

	except GitCommandError as err:
	if self.config.get('fallback_to_build_date'):
	log(
	"[git-revision-date-localized-plugin] Unable to read git logs of '%s'. Is git log readable?"
	" Option 'fallback_to_build_date' set to 'true': Falling back to build date"
	% path
	)
	commit_timestamp = time.time()

The traceback actually already has the correct solution (last line):

git config --global --add [safe.directory](http://safe.directory/) /workspace/source-repo'

I created the issue to remember when I next touch this plugin, to improve the error handling, but because the "Solution is not fallback to builddate".

This issue pops up for people with newer versions of git , and the solution (that I also contributed to the mkdocs-material docker image) is basically these two lines:

# Trust directory, required for git >= 2.35.2
# Run this inside the root of your project
# Remember to update any CI/CD pipelines also
git config --global --add safe.directory /docs
git config --global --add safe.directory /site
