Bug: No comma after SHOW_CHROME_EXTENSION_BANNER

Tested with jitsi-meet-web 1.0.3928

Packaged file /usr/share/jitsi-meet/interface_config.js includes this line:

SHOW_CHROME_EXTENSION_BANNER: false

(without “,” ending)
This produces that uncommenting posterior parameters makes web UI to fail.
@rishabhchd19 told this problem in thread #19218

Yes this is the issue I also noticed in recent update.
