Enhancement Requests - Customize "Plex username or email" prompt

[dlhall111]

Not sure how common this use case is for other folks but I only have one user that's connected via their own Plex account, all others are managed/home users. Which means when I publish Wrapperr and start getting users in there they're often confused about what to type into the prompt since it says "email" and I guess that's a more obvious term than "Plex username" for them - but then of course their email will not work since they're a managed user.

If this could be customized like some of the other strings I would set it to "Enter your Plex profile name" since that's what they see when they pick a profile from within Plex itself.

Thanks for your consideration and for the awesome project! :)
