Disable docker reddeer tests

Reddeer no longer resolves with latest 2024-09 simrel and fails with:
```
[ERROR] Cannot resolve target definition:
[ERROR]   Software being installed:
org.eclipse.reddeer.eclipse.feature.feature.group 4.7.0.v20230906-0832
[ERROR]   Missing requirement: org.eclipse.reddeer.junit
4.7.0.v20230906-0832 requires 'osgi.bundle; org.json 1.0.0' but it could
not be found
[ERROR]   Cannot satisfy dependency:
org.eclipse.reddeer.eclipse.feature.feature.group 4.7.0.v20230906-0832
depends on: org.eclipse.equinox.p2.iu; org.eclipse.reddeer.junit
[4.7.0.v20230906-0832,4.7.0.v20230906-0832]
```

There is ancient docker tests feature being deleted too as it referenced
the tests but was not published in any way thus useless nowadays.
