MB-9717 Make local installation easier with a script

[monfresh]

For those who prefer to use Homebrew instead of Nix, rather than make
them perform a bunch of steps manually, we can automate the entire
setup with a single command.

Here's how the script works:

1. There's a trussworks/fresh-brew repo that has a main script that
   only installs the bare minimum anyone wishing to contribute would need: Homebrew (which also
   installs Apple's Command Line Tools if they're not there yet), and Git.
   I also threw in GitHub's CLI tool since it's a nice thing to have. This
   script is idempotent, meaning it can be run over and over safely. If you
   already have Homebrew, Git and the GH CLI, it will automatically update
   them.
2. The script also allows you to customize it by adding more tools you
   want to install, or commands you want to run, on a project by project
   basis. To install additional tools that you want to install via
   Homebrew, you add a Brewfile.local to your project's repo, like the
   one I added here that installs yarn and nodenv. Additional
   commands and bash scripts go in a fresh-brew.local file, like the
   one I added in this PR which uses nodenv to install the Node version
   specified in the local .node-version file. This means that if we
   want to update the Node version for everyone, all we need to do is
   update the .node-version file, and people can run the fresh-press
   script from the fresh-brew repo and it will update everything
   automatically.

Notes for reviewers

To test this, if you already have nodenv and/or yarn installed,
please uninstall them. Then, pull this branch to your machine, and run
the command in the README:

bash <(curl -s https://raw.githubusercontent.com/trussworks/fresh-brew/main/fresh-press)

This single command should take care of the entire setup, and should
automatically run the server and launch the docs repo in your browser.

Should the fresh-press script reference the Truss forked version instead of the original?

This worked for me. I'm not using nix someone with nix might want to review.

I cloned the repo and ran the bash script. There were a lot of updates to install and then MilMove Docs opened in browser.

I did not remove my yarn installation and the script worked. So that would also be good to test.

I also threw in GitHub's CLI tool since it's a nice thing to have.

I think it might be good to make this one optional? Like a prompt asking if they want it. Mainly because I think it'd be good to keep this down to the required things so we aren't installing things on people's machines that they don't want.

I also agree that the script should likely be updated to point at the Truss repo, thought that'll be in the fresh-brew repo.

I tested this locally with nix disabled and after uninstalling yarn, but I couldn't get rid of nodenv because of other dependencies with my setup. It seems to work fine though (and in fact calls out a bunch of things I might have wrong with my homebrew setup haha). I seem to be able to switch between this and nix fairly easily so I think it's working well in that respect.
