Temporarily use exoplayer2-hosted SVGs in media3 javadoc

The media3-hosted versions of these SVGs were removed due to a change in
the way the reference docs are generated. While work on getting them
hosted on developer.android.com, this change simply links to the
(identical) exoplayer2 versions in order to fix the media3 docs.
