Remove adjust links (Fixes #11698)

[alexgibson]

One-line summary

Removes Adjust links and replaces them with native app store links and default campaign parameters. Uses this spreadsheet for reference (Mozilla access only).

Significant changes and points to review

There are still adjust URLs wrapped up inside some QR Codes on certain pages, but that will have to be handled in a separate issue. But with this change there shouldn't be any more adjust links in HTML pages. Some additional searching / checking would be helpful to make sure I didn't miss any?
