This only affects the default SDK level that Robolectric tests run at.
Also upgrade the Robolectric version to 4.14.1 to pick up
4f32042afe
which is needed for async `ShadowMediaCodec` support (the default in
ExoPlayer from API 31+).
Some tests fail on Robolectric at API 31. This change configures them to
continue running on API 30, so the failures can be investigated and
fixed in follow-up changes.
