linting: fix typos, add toml validation (#7007)

- adds the `toml` plugin to the `eslint` linting → expect to have `options/setting/config.toml` by #6862
- fixes `make lint-codespell` commands
- related concerning `codespell`: #3270
- info: codespell check is and was not activated in the workflows (could maybe, runs only few seconds on my system)
