Remove non-existent category from `parlance`. (#592)

Unfortunately `text` is a hallucinated category, as can be verified at
https://crates.io/category_slugs.

Annoyingly `cargo publish --dry-run` did not catch this earlier. The
verification is only done during a real publish on the server.

Prepare for 0.5.0 release of Parley (#374)

- I have checked that the changelog is up to date (and determined that
no new entries were necessary). A couple of PRs are not listed, but
they're just adding derives for `Debug` or `Hash` impls for types which
doesn't seem useful to log in the changelog to me.
- I have run `cargo update --ignore-rust-version` and `cargo upgrade
--ignore-rust-version`
- I have bumped the versions of Parley and Fontique to `0.5.0`
