[FEAT] Improve the English words on the "Onboarding" page

Feature description:

The words "publisher or a midweek student" or "baptized brother" may cause some confusion when selecting the correct option. This could be improved.

A test was done with a sister and she chose the "baptized brother" option. The other option doesn't make sense because it's for baptisms too. And she's baptized, so...

It was created by @ux-git 3 change options.

Personally, I liked the 2nd option.
