Feature summary:
Alias Special:UnblockUser and Special:UnblockIP to Special:Unblock
Use case(s):
BlockUser and BlockIP are both aliased to Block, so it makes sense for similar aliasing to Special:Unblock.
A user might type the wrong name.
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:
'Unblock' => [ 'Unblock' ],
Currently at line 543 to:
'Unblock' => [ 'Unblock', 'UnblockIP', 'UnblockUser' ],
