Proton Pass' free tier should include minimal password change history.

With this change, Proton Pass free would retain the previous password for a site - only one password, not full history. This would also incorporate minimal history for generated passwords (ex. last 1-2) to avoid situations where users generate/change passwords but they are not properly updated in Proton Pass.

Well aware that there needs to be a distinction between free and Pass Plus to encourage paid adoption. However, eliminating all history in the free tier causes frustration which impacts broader adoption.
