Add Flox as an installation option

[bryanhonof]

you-get is available and working on Flox today.
I tested it out as follows.

$ flox init
✨ Created environment 'tmp.nmbKH8f71c' (aarch64-darwin)

Next:
  $ flox search <package>    <- Search for a package
  $ flox install <package>   <- Install a package into an environment
  $ flox activate            <- Enter the environment
  $ flox edit                <- Add environment variables and shell hooks

$ flox install you-get
✅ 'you-get' installed to environment 'tmp.nmbKH8f71c'
$ flox activate -- you-get --version
you-get: version 0.4.1700, a tiny downloader that scrapes the web.
