no issue
Since `ember-moment@10.0` it's not been necessary to use the `ember-cli-moment-shim` package, with `moment` instead being usable directly via `ember-auto-import`. Getting rid of the shim package is necessary for compatibility with `embroider`, Ember's new build tooling.
- dropped `ember-cli-moment-shim` dependency
- added `moment-timezone` dependency and updated all imports to reflect the different package
- worked around `ember-power-calendar` having `ember-cli-moment-shim` as a sub-dependency
- added empty in-repo-addon `ember-power-calendar-moment` to avoid `ember-power-calendar` complaining about a missing package
- added `ember-power-calendar-utils` in-repo-addon that is a copy of `ember-power-calendar-moment` but without the build-time renaming of the tree for better compatibility with embroider

- `miragejs` has been extracted to a framework-independent library, the re-exports of `miragejs` elements in `ember-cli-mirage` have been deprecated making our test logs very noisy
- added `miragejs` as a top-level dependency
- updated all relevant imports to pull from `miragejs` instead of `ember-cli-mirage`
