Add more Git features about bat

[eth-p]

I've even been looking in other projects like bat-extras hoping this feature is somewhere

With batdiff (as part of bat-extras) specifically, yeah, it doesn't support --staged. I haven't had the chance to work on that yet, but you could probably use a shell alias in the meantime? git diff --staged | bat -ldiff.

Alternatively, I highly recommend delta for git or diff-related pretty printing. It uses a fork of bat under the hood, so it'll respect your chosen theme too.

I've been looking around for a bat --staged option and this is the first spot I see it crossed out which is a little sad bc this project is very cool and --staged is a very important flag for git.

I've even been looking in other projects like bat-extras hoping this feature is somewhere:
eth-p/bat-extras#91

Any chance I'm missing something and can be directed towards how to use something like bat --diff --staged?

I did see the progress on batdiff #940
which again was cool but unless I'm missing something does not support --staged.
