You can now start, stop, and update workspaces. Since you can start workspaces yourself now, I marked non-ready states as unreachable, which prevents JetBrains from overriding with their own text ("disconnected" and "connected"). So now you will be able to see "stopped", "starting", and so on, which is nice. For the ready states you will still see "disconnected" or "connected" unfortunately. Ideally this would be displayed separately from the workspace state. This also means you have two clicks instead of one to connect to a workspace, but I felt like it was worth the tradeoff to (mostly) see the actual workspace state, and it does match the current Gateway flow. If we can separate the states visually then we can bring back the one-click behavior.

Weirdly, you can still press connect when environments are unreachable, but this will not actually work. It does not actually even attempt to connect, because if it did the workspace would start via the cli, so it seems to just be a no-op. Not sure what the idea here is, we may have to consult JetBrains.

Stacked on#487, for the CI fixes.

Closes#485
