Add Subresource Integrity attribute to CSS and JS assets.

This prevents compromised or malicious CDNs from modifying GitLab's assets. The hash provided by Rails is compared to the hash of the asset the browser has downloaded. The browser will refuse to execute/parse the assets if the hashes don't match. SRI is currently implemented in Firefox, Chrome, and Opera.

This doesn't apply to the dynamically-generated per-page JavaScript due to [a bug in sprockets-rails](https://github.com/rails/sprockets-rails/issues/359). Unfortunately until there's a fix available we won't benefit fully from a security perspective.

It's more secure. More information is available in #18230 and on MDN:
https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity

Fixes #18230

Update docs based on customer upgrade from 4.0

## What does this MR do?

Adds helpful notes to early upgrade docs. Without these helpful hints it will be really hard for most people to upgrade from early versions to later versions. 

The tip about doing database migrations to version 6.1, then migrating iids, then migrating the database all the way was based on a tip from https://github.com/gitlabhq/gitlabhq/issues/7869. It worked really well!
