fix: Remove Moment.js dependency

[Koenkk]

Remove dependency on Moment.js as it's considered legacy and we can easily replace the functionality that is used with a simple function.

This is potentially breaking as we don't support all tokens supported by Moment.js (but I don't expect it's used). Let's add more once we find users using it.
