Remove the shopping components
All of it seems to still be pref'd off behind `browser.shopping.experience2023.enabled` and `browser.shopping.experience2023.optedIn`, still we should checkout what is happening there.
I am opening this instead of opening separate tickets for everything shopping related from the audit.
[All "Shopping" component tickets, for reference.](https://bugzilla.mozilla.org/buglist.cgi?resolution=FIXED&resolution=INVALID&resolution=WONTFIX&resolution=INACTIVE&resolution=DUPLICATE&resolution=WORKSFORME&resolution=INCOMPLETE&resolution=SUPPORT&resolution=EXPIRED&resolution=MOVED&component=Shopping&classification=Client%20Software&classification=Developer%20Infrastructure&classification=Components&classification=Server%20Software&classification=Other&query_format=advanced)
EDIT: old title -> `Review "Shopping" related stuff`
