Can we remove this entire method now and use Fido2ContentScript.PageScriptAppend in the places where it's being called?

[dan-livefront]

We could, but that file includes several comments explaining the reasons behind the delay for Manifest V2, as well as the actual implementation of that delay. Since the append operation is still delayed, I felt it was clearer to keep the current name for consistency and clarity.
