Translate `FAQ` in v2 guestLayout and mainLayout?

[pdehaan]

Q: Does FAQ need to be translated?

git grep -n ">FAQ<" src | cat

src/views/guestLayout.js:76:        <li><a href='https://support.mozilla.org/kb/firefox-monitor-faq' target='_blank'>FAQ</a></li>
src/views/mainLayout.js:110:        <li><a href='https://support.mozilla.org/kb/firefox-monitor-faq' target='_blank'>FAQ</a></li>

PS: See GitHub discussion thread below for more details and flavor.
