Add support for JetBrains EAP IDEs (v2022.3)

Description

Now that IDEA/PyCharm/PhpStorm/GoLand latest version is v2022.3 in Gitpod, we can add support for JetBrains IDEs v2022.3.

All code changes were done to accommodate the API differences between v2022.2 and v2022.3. There were no logic/flow changes in the plugin.

How to test

1. Access the Preview Environment of this PR
2. Open a workspace using the Stable Version of IntelliJ IDEA and check if the Control Center is being displayed correctly and that the IDE shows no errors about Gitpod Plugin.
3. Do the same as Step 2, but now using the Latest Stable Version of IntelliJ IDEA.

Release Notes

Gitpod Plugin was updated to work with the JetBrains IDEs v2022.3 (EAP).

Closed in favor of #13400, which is based in a previous commit and should have the Preview Environment working properly.
