Allow SimpleLogin alias creation to use randomized aliases

Feature name

Allow SimpleLogin alias creation to use randomized aliases (for custom domains).

Right now it is forced to have the website hostname without TLD before the @. I don’t want this, I want to be able to easily generate and alias within Bitwarden when creating a new password entry for a new website. The created alias shouldn’t (in my opinion) disclose what its use-case is for.

Feature function

I would like the option to not generate aliases as [email protected] but [email protected] with my custom domain through SimpleLogin.
