Description

This updates docstub to the most recent version: 0.6.0. I've allowed for patch releases but excluded >=0.7.0, because those might introduce new features. By pinning we can more closely control our CI.

After the discussion during our summit I removed the skimage specific array syntax (scientific-python/docstub@9d546a8). We opted to adopt the less ambiguous one from scikit-learn.

This is the reason the number of reported errors goes up. There'll be many more expression that docstub doesn't allow. I recommend addressing these in a separate PR. So it's clearer how the allowed number of errors changes.

This was brought up in #8011 (comment).

@mkcor feel free to merge this if you approve.
