fix: fixes FAQs on pages that use ContentfulPage

[eddieferrer]

• Adds a wrapper component that can be used in conjunction with KvFrequentlyAskedQuestions for contentful pages

VUE-790

Fixes FAQ section wrapping for pages that use Contentful page and FAQs (for example lp/climatechange). With this PR, you can either use:
Contentful/FrequentlyAskedQuestions.vue

• Will wrap the FAQ section with a page container with a max width and a section background

or KvFrequentlyAskedQuestions

• Will not wrap questions, and you will not be able to apply a sections background (I checked all uses of this in one off pages like /donate/supportus and non of them use the section background anyway)

This should be hotfixed or we should hotfix a revert to #3328 since it is affecting the landing pages for the causes MVP.
