User is currently only shown password constraints when registration fails because of invalid password.

Hi can I take this up? I'm a first time contributor.

[mekarpeles]

Sure thing! I think there was an attempted out request in this in the past; I can try to link it here

[sbshah97]

Alright I'll look into that before putting up my PR

@mekarpeles this was the required string file! https://github.com/internetarchive/openlibrary/blob/master/openlibrary/plugins/openlibrary/i18n/account/register/strings.en

@mekarpeles sent a PR. Kindly review!

The password requirements have disappeared.

I think we do / will show them only when there is a problem with the password as opposed to every time.
