Fix/include ide and remove unused packages [MTT-8034] by Elfi0Kuhndorf · Pull Request #166 · Unity-Technologies/com.unity.multiplayer.samples.bitesize

Also I updated some other packages, please let me know if I should NOT update other packages than the IDE packages.

You should not. Updating packages is a potential breaking change that is usually done in 2 specific cases:

  1. When the package version you're upgrading to has a fix/feature you need
  2. When the editor forces you (I.E: when upgrading Unity from one version to another)

Can you please revert the changes so that only IDE packages are updated? (you'll need to adjust the changelog entry too)
