**Bug description**

Error response from daemon: manifest for unityci/editor:ubuntu-2022.3.15f1-android-2 not found: manifest unknown: manifest unknown

I saw that it was reported before for v1 here https://github.com/game-ci/unity-orb/issues/58
it changed to 2 here https://github.com/game-ci/unity-orb/pull/59
but why not specify the image version from the config file?
now there is no version 2 for 2022.3.15f1 it is 3.0.0

Start by tracing how the Unity image tag is selected from the configuration, then compare the behavior with issue #58 and pull request #59. Verify the configured Unity version resolves to an existing image tag, including the reported 2022.3.15f1 Android image.
