This adds the esy lockfile and build dir to the vendor list.

Linguist doesn't acknowledge the .lock extension, so adding .esy.lock as a vendored file is redundant. Instead, we mark such files as generated, which is handled in lib/linguist/generated.rb.

Could you give a link that explains more about _esy build directories?

I only see composer.lock, Cargo.lock, Pipfile.lock and (Gopkg|glide)\.lock also side note.
https://github.com/github/linguist/blob/50005d6e607d956479f03e378c9c54aed03e7a6e/lib/linguist/generated.rb#L364 we have the two !! we didn't have it here https://github.com/github/linguist/blob/50005d6e607d956479f03e378c9c54aed03e7a6e/lib/linguist/generated.rb#L430

for _esy The better link I have found is https://esy.sh/docs/en/how-it-works.html#local-build-store
but it deal only with some specific folder. Maybe @andreypopp can give you more information/link because it is the main developper (2084 commits vs <113 commits for others)

Okay, _esy looks good.

All we need to do now is remove the .esy.lock file from vendor.yml and move it to lib/linguist/generated.rb, like I said.

_esy should not be committed avd is ignored in all "official" templates.

esy.lock is a directory with a bunch of files that describes the current snapshot including overrides of some packages. When something is updated there is often a huge amount of changed files here.

If we should add test I want to add theese one https://gist.github.com/Et7f3/c36059408ffb2f648618e798b54d1d6f
