loginform.html with autocomple for multiply sources

[Vittore Zen]

Hi. 

I created the loginform.html with a little improvement: the sources field is now a dropdown list with a search field (autocomplete like select2).

The code is at this StackOverflow post https://stackoverflow.com/questions/79088534/cas-login-page-with-select2-for-sources/79093461#79093461

I don't know if this can be an official suggestion.

Bye.
