Remove explicit clnvm run

- Removed `RUN uv run clnvm get-all` since it fails with `No such file or directory (os error 2)` and is redundant, as the command runs later with `gltestserver run`.

- Set `GL_TESTING_IGNORE_HASH` to False to suppress the warning: "Checking the hash of remote versions is disabled, which is unsafe. Try to unset GL_TESTING_IGNORE_HASH."
