Use secure unity version (#321)

* chore: update Unity version from 2021.3.45f1 to 2021.3.45f2

Older Unity version had the security vulnerability, so we update it

* feat: add dynamic version display in editor window settings

* refactor: remove manual license file handling from Unity test workflow

* Revert "refactor: remove manual license file handling from Unity test workflow"

This reverts commit a6ab3d982e792039c01a4afd353e61c7e22a2c3c.

* feat: add Unity license credentials to Docker containers in CI workflow

* refactor: replace manual Unity license activation with game-ci/unity-activator

* refactor: simplify Unity CI setup by removing game-ci activation and using built-in license handling

* fix: improve Unity license activation in CI by using unityci image's built-in activation flow

* refactor:  activate once in a temporary container, then reuse the license in the long-running container

Now we got the license secret to be read, we got this error: "Machine bindings don't match". So it seems that the license I generated locally can't be used.

So we need to activate the license within the container

* Revert "refactor:  activate once in a temporary container, then reuse the license in the long-running container"
