lsp-packages: add package pyrefly

[FKouhai]

basically adding the pyrefly package which can be used as an lsp for python: https://pyrefly.org/

This list should be following nvim-lspconfig's list of servers.
Apparently, pyrefly is not listed there (yet). At least, not in the version currently shipped in nixvim's nixpkgs revision.

thats interesting, I thought that was already part of the nvim lspconfig servers.
neovim/nvim-lspconfig#3856 I see that PR upstream got merged a few months ago

Our lspconfig generation script is still looking for the "old" config files at lua/lspconfig/config/*.lua.

That's because some servers don't yet support the new configuration style.

We need to update our script to check both the old and new locations.
