Problem:
Its confusing that https://www.wikidata.org/wiki/Special:ItemDisambiguation redirects to https://www.wikidata.org/wiki/Special:BlankPage
Acceptance criteria:
- Special:ItemDisambiguation redirects to Special:DisabledSpecialPage instead of Special:Blank
Notes:
Initial reason for the creation of DisabledSpecialPage, see T200185: Create a Special:DisabledSpecialPage to be used instead of Special:BlankPage
