v0.4.0

[ggwpez]

Closes #3

Changes:

• Add FormattedWarning. It is possible to directly instantiate this enum, or use new_deprecated(name, note, span). The builder pattern is not used, since there are only three fields and none are optional.
• 🚨 Remove Warning::new_raw as Warning became an enum and can directly be constructed. This is more in line when adding more warning types later.
• Move crate to workspace and add UI tests.
• Update docs.
