ML Agents package has incorrect deprecated label and so can't be installed

Steps to reproduce:

1. Open a Unity Project
2. Open Package Manger via Window > Package Management > Package Manager
3. Navigate to the Unity Registry tab
4. Find and select the ML Agents package

Actual results: The package has the red deprecated label, which means it is not installable.

Expected results: The package has the yellow deprecated label. This means that it has reached end of life, but is still installable. As the package isn't broken (as the text on the package says 'it will keep working as is'), the red deprecated label is not correct.

Reproducible with versions: 6000.2.0a1, 6000.1.0b4

Not reproducible with versions: - 

Can't test with versions: - 

Tested on (OS): Windows 11

Notes: 

• The bug might be that the wrong ML Agents version is showing for 6.2 and 6.1. As they show 2.0.1, whereas 6 shows 3.0.0. If this is the case, then the bug is instead that in those version, it is showing the wrong version by default.
• The correct Affects Version/s does not seem to appear in the list given on Jira, so this field has not been set correctly. As it is a required field, 2.0.0 was put for now.
