Set Autocomplete Off on Login Form

[geraj1010]

Closes #44019

Updated main Javascript to apply autocomplete="off" to both username and password inputs on login page. This will help prevent the browser from providing hints for the username (and password), as requested in the Issue.

Based on Flask-AppBuilder source code, i.e. https://github.com/dpgaspar/Flask-AppBuilder/tree/master/flask_appbuilder/templates/appbuilder/general/security (see login_db.html and login_ldap.html), this should work for both AUTH_DB (default) and AUTH_LDAP authentication, since they both apparently use the same HTML elements in the form.

Nice, tested locally, working as expected.

Should we target main and backport instead of specifically targeting v2-10-test. When changes are compatible I believe main then backport is better to limit drift between the two branches, I tend to directly target v2-10-test for changes that are completely different and incompatible with main anymore. @ephraimbuddy what do you think ?

I agree with you. Main then backport, for changes that are a bit compatible otherwise a different PR targeting the test branch would be better

Closing this PR, since we decided to push this one to main and backtrack to v2-10-test.
