Update Camera-Streamer default branch

[BryanSmithDev]

Appears that Camera-Streamer repo now uses 'main' instead of 'master'

We are already aware of that and this is basically a duplicate of #137. I will close it for the same reason.
There will be soon an update to main branch, but Bookworm exclusive at first, as Crowsnest fails to build on Bookworm with master branch (#188). As we (more like me) currently think that the Bookworm Raspberry Pi image is more like in a testing phase for the software inside the klipper universe.
So we will only update it for Bookworm that those people with Bookworm can use Crowsnest again. The Bookworm people will be like a testing group for this. We won't release it for Bullseye as we want to do enough testing on it first that we can assure that there aren't any issues like breaking changes or maybe missing features.

Btw updating it only like this won't make it possible to easily connect directly via the ip and you will have to use the /webcam endpoint to connect. This is because of the new parameter --http-listen=127.0.0.1, so the no_proxy=true option would need an update for camera-streamer too.
I think this is a good example of an unforeseen issue that could cause issues by just updating the branch.
Also this change will only work for new installations, so we need something for already installed systems too, that there won't be something like the update from Crowsnest v3 to v4 again.

Apologies. I checked prior pull requests before submitting but must have overlooked #137

Thanks for your work on Crowsnest / Mainsail
