fix(transformer): find last modified date form commit on submodule

[dralagen]

when the content folder has a submodule git, the relative path start in content folder and not root folder of quartz

example of repo use a submodule : https://github.com/dralagen/notes.dralagen.fr
The submodule is private to publish only public note and keep some private or draft not visible.

can you see if 771110a works for you locally first?

I need to calculate the relative path from the repository.
In my case, ctx.argv.directory is equal to content folder, and file.data.filePath is equals to content/index.md.

if don't do modification, I have this result :

Warning: content/index.md isn't yet tracked by git, dates will be inaccurate

calculate workdir where we assign repo and also add an error for when workdir is undefined

[dralagen]

workdir return undefined if repository is bare. I thinks, we have other problem on build, like don't find index.md.

calculate workdir where we assign repo

You want to set the value of repo.workdir() to variable ?

[jackyzha0]

yes because path.relative(undefined, fullFp) will cause problems

[dralagen]

ok, thanks for review.

Suggested change

	repositoryWorkdir = repo.workdir() ?? ""
	repositoryWorkdir = repo.workdir() ?? ctx.argv.directory

[dralagen]

I don't use ctx.argv.directory as default value, because the major usage is the root folder is the workdir of repository and ctx.argc.directory is valued to content.
I want to set a default value to make path.relative(repositoryWorkdir, fullFp) equals to fullFp
