Compressed WAVs are not supported, contrary to the documentation

[psychicteeth]

Your Godot version:
4.3

Issue description:
The importing audio docs suggest that compressed WAVs are supported by Godot, but when trying to import IMA-ADPCM audio files, Godot responds with the following error:
Format not supported for WAVE file (not PCM). Save WAVE files as uncompressed PCM or IEEE float instead.

The docs should be updated to mention that compressed WAVs are not supported.

The documentation is unclear, it supports compressing imported WAV, but doesn't support loading compressed WAV
