"Firefox Translations" should be coded together as a product name in Fluent

[peiying2]

Description

It was brought to my attention that four strings released earlier separate the brand and the product name rather than treating them as one.

Steps to reproduce

{ -brand-name-firefox } Translations should be changed to { -brand-name-firefox-translations }. We already have an entry for the full product name in the brands.ftl file

Expected result

Update all the { -brand-name-firefox } Translations to { -brand-name-firefox-translations }
