:sparkles: What kind of change does this PR introduce? (Bug fix, feature, docs update...)

Updates ExoPlayer on MAUI to 2.19.1

@martijn00 This will probably need ExoPlayer.Container to be published on NuGet, else things like MP4's and stuff won't play because there's some class in there that needs to be existent.

There's also ExoPlayer.Muxer, I have no idea what this does but it was added 2.19 so I added that to the solution too.

@ArchangelWTF thanks! I've merged and released a new version.

Do you want to have a look at the dependabot updates to see if we need to do anything?

@martijn00 I think I can, could you set me as a collaborator so I can re-run their CI/CD at will?
