fix: add container-safe flags to Edge entrypoint

[nbucking]

Add --disable-dev-shm-usage and --disable-gpu to prevent crashes in webtop/container environments where /dev/shm is limited and no GPU is available.

I recommend passing --shm-size=1gb in all our containers (this is in the readme) and many users including me use a GPU with these apps. The only thing that does not work is nvidia accel as the libs will not be present but AMD/Intel work great. Also disabling shm while it makes it "work" is another untested codepath in chromium (non default) and has performance implications as they exepct shm to be there. You definitely will not save any memory doing it the ram will still need to be used it will just likely be in a more manual assign new pointer for each action vs using a known ring buffer in shm.

So these would not be great defaults.
