Make tea magic hook work on fish

[pkmuldoon]

Looks like a great project! However, when using fish, after install I get

  want magic?

  tea’s shell magic works via a simple hook function in fish
  it’s not required, but we do recommend it.

  │ docs https://github.com/teaxyz/cli#usage-as-an-environment-manager
sh: line 362: ~/.config/fish/config.fish: No such file or directory

The file ~/.config/fish/config.fish does exist and is writeable. This is on Mac OS Ventura 13.0.1 on the ARM M1 Max with fish shell version 3.5.1

I'm running asdf but that doesn't seem to be impacting. BTW to get the install script to work on Fish, I had to do: sh < (curl https://tea.xyz | psub)

Thanks for all of your awesome work!
