chore: remove typos CLI tooling (#78)

Remove typos configuration and packages:
- Remove typos.enable and typos.configFile from treefmt.programs
- Delete typos.toml configuration file
- Remove typos and typos-lsp from devShells buildInputs

The typos tool is no longer needed for this project's workflow.
