As I haven't used the custom color scheme I created previously in ages I
think I don't need it anymore. Also, as I'm not using kitty as my
terminal emulator I can also remove the custom script I had to export my
nvim colors to kitty format.
* Add export-kitty-colors.lua scripts to colors folder
Exports the current colorscheme to a kitty color scheme
* Modify peel-enhanced.vim theme
* Add lsp signature help
