chore: update flake.lock and remove unused language servers

- Updated `flake.lock` with new revisions and hashes for `flake-parts` and `nixpkgs`.
- Removed `dhall-lsp-server`, `gleam`, and `sourcekit-lsp` from `lib/default.nix`.
- Removed configurations for `dhall_lsp_server`, `gleam`, and `sourcekit` from `languages.lua`.
- Added `foldexpr` and `foldmethod` settings to `vim.lua`.
