Feature summary:
Add aliases for Special:Purge
Use case(s):
Many other special pages have the form verb+object, or verb. It's inconsistent and users may guess wrong if they haven't memorised the names of special pages. In the case of purge, we can talk about "purging the cache" or "purging the page" or even "purging the page cache."
Good first task
There's only a minor change required here to languages / messages / MessagesEn.php to add these aliases. It's literally a change to one line of code to add it to the array:
'Purge' => [ 'Purge' ],
Currently at line 522 to:
'Purge' => [ 'Purge', 'PurgeCache', 'PurgePage', 'PurgePageCache' ],
