Fix a grammar mistake by updating the following two strings to read "These criteria" instead of "This criteria":

• https://github.com/WikipediaLibrary/TWLight/blob/master/TWLight/templates/login_partial.html#L33
• https://github.com/WikipediaLibrary/TWLight/blob/master/TWLight/templates/login_partial.html#L37

Original task
In https://translatewiki.net/wiki/Wikimedia:Wikipedia-library-df39ce-Meet this criteria for automat/en, "criteria" is plural (and in fact there is a list of multiple criteria following this message) so "this" should be "these"; the message should read "Meet these criteria for automatic access".

Similarly, in the accompanying tooltip message https://translatewiki.net/wiki/Wikimedia:Wikipedia-library-574315-This criteria grants you acces/en, "This criteria grants" should be "These criteria grant".

These messages are shown prominently on https://wikipedialibrary.wmflabs.org/.
