[mihar-22]

Note

Low Risk
Low risk: only changes the default playback rate list values (sub-1x rates) plus corresponding tests/docs, without altering cycling logic or media state handling.

Overview
Updates the default playback rate options to use 0.2x and 0.7x instead of 0.25x and 0.75x.

Aligns behavior expectations by updating playbackRateFeature defaults, PlaybackRateButtonCore tests (wrap/cycle assertions), and the PlaybackRateButton documentation to reflect the new rate list.
