Fix setting basic auth config by hand

Hi @morgoth, thanks for this! But this was not supported on purpose, as a deterrent to avoid people setting secret as their password, forcing having to use Rails credentials and providing an easy way to set those via a command.

Not being able to set it by hand as all other configs would make people confuse when they try it (as me ;-).
Also I can imagine people setting secrets via env variable, which for them it won't be possible to use this feature.

I think the README explains it, in case someone is confused 🤔 I'll wait to see if this actually becomes a problem before changing it.
