plugins: rewrite the LSP configuration

- Rewrites the LSP configuration to neovim v0.11+ capabilities in the
  mason.lua file.
- Adapts the completion configuration accordingly.
- Removes lsp-zero unnecessary plugin.
- Removes the nvim-lsp-file-operations plugin that I never use.
- I have been helped by the Kimi language model provided by the Kagi
  assistant interface.
