Add homebrew on Linux and macOS

[ClashTheBunny]

This adds directions that will work when
Homebrew/homebrew-core#105986 is merged. If that is
not merged, we can create a tap and adjust these directions accordingly.

I think I followed the current formatting, but is there a specific markdown linting that is preferred? I didn't see anything in the .github directory.

Checklist

If applicable:

• I have updated CHANGELOG.md
• I have updated the documentation (README.md, docs/, demos/)

This is merged in homebrew and I've used it to install 0.4.0 and head in homebrew.

https://formulae.brew.sh/formula/jj#default and https://github.com/Homebrew/homebrew-core/blob/master/Formula/jj.rb look correct and there are bottles created for them on pretty much every OS.

Should I add something like "we don't release very often, so it may be more interesting to install the --HEAD version."?

Thanks! Does that mean that this is now ready for review?

It just hasn't seemed like it mattered much when I cut release because most people build from head so far, but I'm happy to cut releases more frequently instead of telling people to build from head.

I'd say we keep an eye on jj installs and if there seem to be a bunch from the release, we can cut releases more often. I'm actually amazed there have been 23 installs in the last 30 days...

Sounds good. I'll still cut a release now because it's been so long. Looks like I should send a PR to update that jj.rb file once that's out. Thanks again for setting this up!

Actually, we should add a --bin jj to https://github.com/Homebrew/homebrew-core/blob/5e9c402aa309f6ea49fb7283b91effc2cbb96a95/Formula/jj.rb#L27 to avoid installing fake-editor and fake-diff-editor (until a good alternative to #216 has been merged). Sorry that I didn't notice that until now.

When you cut the release, we can try brew bump:

❯ brew bump jj
==> jj
Current formula version:  0.4.0
Latest livecheck version: 0.4.0
Latest Repology version:  no latest version
Open pull requests:       none

and then it will create the PR: https://docs.brew.sh/How-To-Open-a-Homebrew-Pull-Request#submit-a-new-version-of-an-existing-formula
