cleanup: refactor which-key configuration for cleaner setup (nvim-lua…

…#1102)

- Moved `which-key` configuration from inline `config` to `opts` for better organization.
- Updated the key mappings setup to use `spec` for defining existing key chains.
- Removed deprecated or unnecessary comments and code.

This change aligns with updated `which-key` configuration practices, improving readability and maintainability as recommended by @VlaDexa in nvim-lua#1068.
