feat: add jcaigitlab/asdf-git

[D-Bhatta]

What I want

Please revert remove asdf-git and add plugin for git to registry.

Reason

I use this git plugin in mise on *nix machines, along with the all_compile = true setting, to compile newer versions of git than what comes with the distribution. The benefits are:

• Ease of administration, especially on remote machines. One mise install gets me a full dev environment everytime.
• Using git@latest ensures I encounter the exact same version of git across all machines, all with exact same behavior. This allows full automation of configuration, with no expected differences in behavior across machines. I just copy config files from a remote, and that's it.
• Makes git administration much easier in environments such as WSL2 boxes, where git administration used to be a major pain point. Now it's just mise install and some cp commands to copy configuration files.

Workarounds

I manually injected this plugin on my latest install with mise plugins install git https://gitlab.com/jcaigitlab/asdf-git.git when I got a No repository found for plugin git error, but the added overhead makes the experience tedious for a bit.

I now have to remember to install this plugin manually, instead of having it in my config.toml file and just using mise install to set up an environment on a new machine.

---

I think including a git plugin will make the experience of using mise much better and smoother.

I am happy to write a PR myself if approved.

git is a prerequisite for using mise, it does not make sense to make it available as a plugin and doing so will result in an infinite loop for plugins that call git when using shims, so no, I won't be considering putting it back in

of course if you want to use it, just install it manually
