[video_player_android] Add note about Android platform views known issue (#9312)

Just a README update to flag the [known issue](flutter/flutter#164899) regarding the platform view mode implementation. The issue is affecting [the optional platform view mode](flutter/flutter#86613), but the decision is to go ahead with the release including this note. cc: @stuartmorgan-g.

I'm not exactly sure about the versioning regarding this, but I think it should be visible on pub, so bumping the version is IMO appropriate.
