Some date-time languages are missing

[cool0707]

The localization of some of the date time languages that we added to app.bundle.min.js before is missing (probably due to the merging process when we upgraded Jiti Meet).
I'm trying to submit a PR to upstream, but it's going to be hard to get it approved and merged, so I'll submit the PR here for now.

I'm trying to submit a PR to upstream, but it's going to be hard to get it approved and merged, so I'll submit the PR here for now.

I'm already approved. In the early months of 2020, I fail to push something upstream. This seems to be happen just because the whole project team was overloaded. But recently, I did it again (jitsi/jitsi-videobridge#1550) and it was processed within a few days (by "the" @bgrozev ).

I try to support it by a review.

I thought the PR of upsteram would simply be to add unsupported languages, but I needed to make Moment.js the latest version to add Moldovan.
However, when I update Moment.js to the latest version, the size of the build webpack exceeds the size and an error occurs.
In order to reduce the size, I need to introduce a plugin that removes languages not used by Moment.js from webpack, but for this, I need to build and test environment to work on it.
I don't have a lot of time right now, so I will make these changes when I have more time and then submit the PR again.

Please give me a review when you do.

I wonder if this size is just and arbitrary limit that is defined somewhere.
