Change exposed port for deepforge-stable

[umesh-timalsina]

We should change the shared port for editor.deepforge.org (i.e. deepforge-stable)

deepforge/.deployment/docker-compose-overrides.yml

Line 23 in e384d1d

- "8889:8888"

Since, 8889 is used by the deepforge-latest.

deepforge/docker/docker-compose.yml

Lines 15 to 16 in e384d1d

	- "8888:8888"
	- "8889:8889"

@brollb I have changed the nginx config to proxy pass port 9000 for editor.deepforge.org. I think we should change it here as well.
