Minor typo in questions

First typo I've noticed while making my way through these questions.
Fix a UX issue with the Next button in navigation

The btn-primary class gives this button extra weight such that it might be considered
the intended default action. When answering a question a person may then interpret "Next"
to mean, Submit my answer and move on to the next question.
Fill in some broken links

I've also changed all the gentoo.org links to https. Because recruiting.gentoo.org prefers https it is sensible to link
to https locations where available. This is a highly subjective change and I will happily fill in the links without doing
this if desired.
