Let Tensorboard works in docker

[jim60105]

Thank you for creating this excellent tool. 👍

I encountered an issue with Tensorboard not starting while using Docker, and I have resolved it.

I modified the startup parameters of Tensorboard to work in a Docker environment and skipped calling webbrowser.open() within Docker.

The PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION environment variable is used by the WHAT-IF Tool. I encountered this issue and found a workaround here. Although I have no idea what the WHAT-IF Tool is for.

This PR has only been tested in docker as I exclusively used docker (with Windows Docker desktop) to run kohya_ss.
Therefore, further testing and validation on other platforms is necessary.

Thanks

I will merge the changes into the dev2 branch to validate that all still work fin under windows

That PR broke the solution on windows, I will revert it. Need a better way to detect when it run in docker cause right now it will no longet open the browser on windows.

@bmaltais I beleve that's not a related issue though, since I saw community talking about this issue #1139 before my PR.
Please feel free to pick this commit again when you fix that problem.
