Get ready for @webref/css v7 release, drop alpha flag

Time to give v7 a try in real life, following iterations and discussions in:
#1519

Note: the way we managed alpha versions was somewhat clunky. The version
increment should have appeared *after* the `alpha` flag. This update drops the
`alpha` flag, which means that the first actual published package will be
`7.0.11` and not `7.0.0`.

Plan is to continue to publish v6 for a little while to give consumers enough
time to adjust their code and provide a fallback plan should the new version
turn out to be impractical.

 - The consolidation removes duplicates, merging extended definitions into a single feature. The definition from the latest spec level is used when a feature is defined in more than one level. If you need the definition from earlier levels, please [raise an issue](https://github.com/w3c/webref/issues) to describe your needs!
 - Some of the possible values that a CSS feature could take appeared nested under that feature definition in a `values` key in version 6. Such values are no longer reported in the new version: they were confusing in any case because they did not cover the whole range of values that a feature could take, and could contain values that were not atomic keyword values. Values could be re-introduced when CSS specs are more systematic about them. In the meantime, you will need to parse the feature's syntax (the `syntax` key) to extract keyword values.
 
-Additionally, the package now also exposes a new `index()` async method that resolves with an object similar to that returned by `listAll()`, except that lists of features under each category are indexed by feature names. For scoped features, the feature name is used as identifier when it is unambiguous. If a  feature is defined differently for different scopes, the feature name is completed with the name of the first scoping feature to disambiguate. For example, `type() for @function`, `type() for attr()`.
