Remove title attributes: wp-login.php

[afercia]

See #24766 for some background. In the login screen, there are a couple of title attributes:

They serve no useful purpose and add noise for screen reader users.

Also, discussed a bit with the Italian polyglots team, they're difficult to translate. While in English there's (maybe?) a subtle irony in a sentence like "Password Lost and Found", the current Italian translation is "Ufficio oggetti smarriti - Password" which sounds a bit weird. I guess it's not so easy to translate the tone of this sentence in other languages too.

I'm not opposed to a bit of irony and in core there are some examples of irony I appreciate ("Slow down cowboy ... ") :) but in this case I'd propose to just remove these 2 title attributes.

Agreed.

In 35846:

Accessibility: remove no-purpose title attributes from the login screen.

Also, it's hard to convey the ironic tone of the sentences used for these title attributes in languages other than English.

Fixes #34943.
