Screenshot of console output from within Safari referencing incorrect API

Calls to WebAuthn's `navigator.credentials.get()` outside of a user gesture errors out as expected. However, the console warning output from this operations mentions "navigator.credentials.create":

> User gesture is not detected. To use the WebAuthn API, call 'navigator.credentials.create' within user activated events.
Console output generated by a call to `navigator.credentials.get` should reference "navigator.credentials.get" instead.

This appears to be caused by a recent change to `WebAuthenticatorCoordinator::processingUserGesture()` that hardcodes "navigator.credentials.create" into the message:

https://trac.webkit.org/browser/webkit/branches/safari-611-branch/Source/WebKit/WebProcess/WebAuthentication/WebAuthenticatorCoordinator.cpp#L112

The following LayoutTests confirm that the same incorrect message is used for `navigator.credentials.get()` user gesture issues as well:

I should clarify that this is observed in Safari 14.1 on macOS 11.3
