Should docs include bit about adding link between fd and fd-find for Ubuntu and Debian systems.

I am a real newbie when it comes to nvim, lua, and even Linux itself. When trying to get the telescope extension to work, none of the .env files were showing up. I copied the code from the extension, ran it, and got the "fd not found" error (I assume this would have been easier if I had run it in debug). Either way, running the command ln -s $(which fdfind) ~/.local/bin/fd fixed it. I'm not sure if anyone else has run into this issue, but I think it might be helpful to include a note in the docs.
