don't use a path in NVIM_APPNAME

[RoryNesbitt]

This will let NVIM_APPNAME stay just a name, meaning it will work with nightly (relevant issue)

It may however break the universe, I don't yet know. I usually try to not touch XDG directories, but I think using a path in NVIM_APPNAME would theoretically have the same issues and that's why they don't want to support it.

Right now using a path works for stable, and the dev branch should^TM work for everything.

Installation:

curl -o ~/.local/bin/dotfyle https://raw.githubusercontent.com/RoryNesbitt/dotfyle-cli/dev/dotfyle
chmod +x ~/.local/bin/dotfyle

The dotfyle upgrade command will always pull from main, even if used from the dev branch. This can be used to get back to the normal version once this hack is no longer required

[RoryNesbitt]

No longer required as of neovim/neovim#25233
