fix(core): implement missing --print flag for nx graph command (#31406)

Browse Source 
## Current Behavior

The `nx graph --print` flag is documented and shows in CLI help, but
when used, it opens the graph UI in a browser instead of printing the
dependency graph to the console.

## Expected Behavior

With this PR, `nx graph --print` correctly prints the dependency graph
JSON to stdout in the terminal and exits, matching the documented
behavior and CLI help description.

## Related Issue(s)

Fixes #30255
