* remove `any` data type for decoration color plugin
The main reason for the `any` type is so that we don't have to parse the
value and can assume that this plugin handles "any" value you give it.
This is useful because `decoration-[var(--something)]` would be
correctly translated to the correct decoration property. However, we
introduce another plugin with the same `decoration` prefix.
This means that now both `textDecorationColor` and
`textDecorationThickness` have the same base utility name: `decoration`.
- `textDecorationColor` had ['color', 'any']
- `textDecorationThickness` had ['length', 'percentage']
This means that `3px` fit both in the `length` data type of the
`textDecorationThickness` plugin and in the `any` data type of the
`textDecorationColor` plugin.
Removing the `any` fixes this.
TL;DR: Only have `any` when there are no conflicting utility names.
* remove utility that doesn't generate css
Having `decoration-[var(--abc)]` is ambiguous because there are multiple
plugins that have a `decoration` utility name. In order for this to work
you have to prefix it with the type: `decoration-[color:var(--abc)]`
which is already tested in this file.
