Problem
Editors are using double spaces to circumvent constraints and our duplicate checks (no two Items with the same label and description in a given language),

It's possible to insert double space characters: https://www.wikidata.org/w/index.php?title=Q4115189&diff=1160235627&oldid=1160235511 (and even more).

Solution
To prevent a reduction in data quality and redundancy, we must remove the ability for editors to insert double spaces and edits with double spaces are adjusted to single spaces.

Spaces at the beginning of labels, aliases and descriptions are removed when publishing edits.

Acceptance Criteria

• Editors are no longer able to to publish changes with double spaces
