Fixes #5088 #2524 - adding taxonomy related parameters to apidocs

- new param group `taxonomy` for taxable resources
- new param group `taxonomy_scope` for index actions of taxable resources
- pagination and search param moved to a group `search_and_pagination` to reduce duplicities
@isratrade you were right, it was caused by find_by_id vs. find_by_id! I just kept Tomas's re-formatting as it seems more readable.
