Package dependencies preventing an upgrade to Angular 13 or higher

[pjmonks]

I was attempting an upgrade from Angular 12 to 13 for mdm-ui to try and resolve peer dependency issues. The upgrade process involves:

1. Removing the local package-lock.json file
2. Deleting all node_modules already on your local machine (to avoid conflicts)
3. Copy original list of dependencies from package.json before making modifications.
4. Overwrite all package dependencies with latest versions of Angular packages
5. Run npm install
6. Then add back additional and 3rd party packages that the Angular upgrade process does not know about.

However, the process highlighted these package dependencies which will prevent an upgrade to Angular 13 because they do not support the latest version of Angular

1. angular-user-idle
2. jodit-angular

angular-user-idle is no longer supported. The mdm-explorer repo gets around this issue by directly importing the source code (with credit to the original authors) into the repo, maintaining it's own forked copy.

jodit-angular has this open issue for Angular 13 support - jodit/jodit-angular#101 - but has not been completed (as of creating this issue).

Both of these are blockers for an Angular 13 upgrade.

It should be pointed out that jodit-angular is actually just a wrapper around the core jodit package, and the code is minimal (one component) to contain the actual Jodit HTML editor DOM elements. So it is possible, like angular-user-idle, to maintain our own copy of the Angular component wrapper and only depend directly on jodit core.
