feat: add fork remote command

[karolzwolak]

PR Description

The command allows you to quickly add a new 'fork' remote with
replaced owner in the origin URL of the selected remote.

For example:
given url: https://github.com/jesseduffield/lazygit.git
and username: karolzwolak
adds a new remote with url: https://github.com/karolzwolak/lazygit.git

Thanks for the PR, and sorry for the long delay in looking at it.

This is a useful feature, I need it myself frequently. Before I review in detail, a few general thoughts:

• it would be even more useful if it could take a repo:branch specification and create the remote and check out the branch in one go. For example, for this very PR I would click the copy-to-clipboard icon here:
  , invoke the command, and paste. Any thoughts on this?
• I didn't look at the code in detail yet, I only noticed from a cursory look that there are many lines of code related to parsing URIs. Is this really needed? Intuitively I would have thought that the implementation would consist of basically a single line of code doing a regex replace. I may well be missing something here, and I should probably look at the code in detail before asking questions like this.
• How much of this is github specific? For me personally, github is the only hosting service that I have experience with, but lazygit supports a bunch of others (gitlab, azure devops, gitea, bitbucket). I wonder if we need to hook into hosting_service.go somehow to make it work for those, too.

Yes, that's a great follow-up. It should be easy to do, too. I will implement it.

Yeah, I might have gone overboard with the url parsing. I didn't know we had regex support. Regex would work well for ssh urls, but it's a bit more nuanced for http/https urls, but I'll try to simplify it.

I also don't have experience besides github, but I think most other hosting services follow the same owner/repo url pattern as github does, so it should work fine without any further modifications. I might be wrong on this, though.

I'm away from home for about 2 weeks, so I won't be active on this right now.
