Replace storage banners faq links with docs links

What does this MR do and why?

It updates the links in storage enforcement and pre-enforcement banners as follows:

Current URL	New URL
https://about.gitlab.com/pricing/faq-efficient-free-tier/#storage-limits-on-gitlab-saas-free-tier	removed
https://about.gitlab.com/pricing/faq-efficient-free-tier/#next-steps	https://docs.gitlab.com/ee/user/usage_quotas.html#namespace-storage-limit

It also updates the copy inside the banners slightly as suggested by Technical Writing.
