Capacitor Keyboard height incorrect in Capacitor 6

[xanather]

Bug Report

Plugin(s)

Capacitor Keyboard

Capacitor Version

6+

Affected Platform(s)

Android all versions, for older versions (Android 9) the bug is even more severe where no keyboard callbacks are made when windowSoftInputMode adjustPan mode is enabled.

Current Behavior

1. The keyboard height includes the navigation bar height, which makes it kind of useless (its non-consistent and requires manually calculating navigation bar height to make it meaningful) and is a breaking change since it didn't before.
2. There is no callback occuring on older versions of android with windowSoftInputMode adjustPan set.

Expected Behavior

1. Keyboard height should only include the height inserted into the webview.
2. Keyboard callbacks should occur always when windowSoftInputMode adjustPan is set.
