I18N: Use wp.i18n for translatable strings in wp-admin/js/dashboard.js.

* Deprecate the `l10n` property on `communityEventsData`.
* Introduce `version` parameter for `deprecateL10nObject` and backfill the version for deprecated objects in 5.5.0.
* Add a noop version of `deprecateL10nObject` for QUnit testing.

Fixes #51498.
