fix(l10n): Fix l10n issues (linter, brand term)

Because:
* New strings were added to #20126 after l10n review and l10n wasn't notified a number of strings with issues were introduced

This commit:
* Replaces straight apostrophe and quotes with curly quotes
* Replaces a hard coded "Mozilla account" with the appropriate brand term
