What this PR does

Fixes #5150

Ports WPS group from master to v8

Also fixes the problem reported in TerriaJS/RaPPMap#105 where a + icon is shown instead of a bar chart icon for catalog functions in the explorer.

Testing

1. Visit CI instance
2. Expand the Wave energy group from catalog
3. You should be able to see the processes created as new members under the catalog group
4. The info section should show the details of the service

### TODO before merge
Remove unrelated temporary fix to make CI pass

Works perfectly!

Optional extra - it would be great if you add WPS Group to "Add Remote Data" section
