fix(ENGDESK-7173): change the STUN_SERVER port from 3843 to 3478

[DeividVeloso]

Error:

• When it tries to make a video call using vanilla example, the code was returning Codec ERROR

Solution:

• We checked the port from STUN/TURN server and figure out that the port was wrong for the STUN server, so we change the STUN_SERVER port from 3843 to 3478.

📝 To Do

• All linters pass
• All tests pass
• Change documentation based on my changes

✋ Manual testing

1. Access the package/js/example/vanilla
2. fill your credentials and try to make a video call using Chrome Browser
3. You should see your local video and the remote video.
