Rename taxonomy kinds from taxonomy to term, taxonomyTerm to taxonomy

And we have taken great measures to limit potential site breakage:

* For `disableKinds` and `outputs` we try to map from old to new values if possible, if not we print an ERROR that can be toggled off if not relevant.
* The layout lookup is mostly compatible with more options for the new `term` kind.

That leaves:

* Where queries in site.Pages using taxonomy/taxonomyTerm Kind values as filter.
* Other places where these kind value are used in the templates (classes etc.)

Fixes #6911
Fixes #7395

 ### Default Destinations
 
 When taxonomies are used---and [taxonomy templates][] are provided---Hugo will automatically create both a page listing all the taxonomy's terms and individual pages with lists of content associated with each term. For example, a `categories` taxonomy declared in your configuration and used in your content front matter will create the following pages:
