Deprecate the Wikipedia Tile to be removed in 1.11.
Adds the deprecated method, which is also present in Holoviews and Panel. I also added the custom warnings for Holoviews and Geoviews to raise errors when running the tests to avoid overlooking warnings.
Also, using the PR to fix docs and build CI (mostly by accident).
Fixes #623
