Allow adding files to .gitignore

[robert7k]

This feature allows users to add a new, untracked file to .gitignore by using the context menu in the git panel.

Release Notes:

• Added feature to add a new file to .gitignore

Nice idea, wouldn't it be better to use Project::save_buffer or something similar that allows to also modify the .gitignore file on remote?

zed/crates/project/src/project.rs

Lines 2739 to 2742 in eaa1cb0

	pub fn save_buffer(&self, buffer: Entity<Buffer>, cx: &mut Context<Self>) -> Task<Result<()>> {
	self.buffer_store
	.update(cx, |buffer_store, cx| buffer_store.save_buffer(buffer, cx))
	}

Great suggestion, thanks!

I adjusted the code accordingly.

Thanks for opening a PR! +1 to having this as a feature, but I think we could improve the handling of the .gitignore file a bit. Right now the code always opens/creates the .gitignore at the worktree root, which is not necessarily the same as the repository root, since you can open a parent or child directory of a git repository in Zed. We should make sure to edit the .gitignore at the repo root.

Thanks for the review and the suggestion. I changed it accordingly.

Thanks, looking good, just a couple of small things and this should be ready to merge!

[cole-miller]

Thanks! Looks like just a lint or two that needs fixing now.
