fix: moment duration format error

[oguzhanslmtemiz]

Issue: When lobby mode is active, the ui showing the elapsed time gives an error when it comes to the screen. Moment just released a new update and moment-duration-format plugin is not compatible with this version. This plugin will always try to install itself on the root.moment instance, if it exists. source

Solution: Used the moment version of jitsi-meet instead of root. No problem with version 2.29.4
