This previously caused an `UnhandledPromiseRejection` which caused tests not to run. But Jasmine, still reported success.

AJV only support a single schema with the same ID, compiling schemas async can cause a race condition were multiple schemas with the same name as compiled at the same time.
Closes#20847
All TypeScript files have been updated to pass the new eslint-based linting checks. eslint compatible disabling comments have also been added in place of the previous tslint comments.
With this change we update ajv to version 8
BREAKING CHANGE: support for JSON Schema draft-04 and draft-06 is removed. If you have schemas using the `id` keyword replace them with `$id`. For an interim period we will auto rename any top level `id` keyword to `$id`.
**NB**: This change only effects schematics and builders authors.
This change provides the first schema validation error to a prompt provider when using a prompt definition's `validate` function. This allows a prompt provider to show additional context to a user when an entered value is invalid.
BREAKING CHANGE:
Deprecated `isObservable` function removed. As an alternative, use `isObservable` from the `rxjs` package.
NOTE: This change does not affect application development.
BREAKING CHANGE:
Deprecated `@angular-devkit/core` terminal API has been removed. Use 3rd party packages like chalk, colors or ansi-colors instead.
**Note:** this changes doesn't effect application developers
BREAKING CHANGE: deprecated API's `ModuleNotFoundException`, `ResolveOptions`, `resolve` have been removed. Use `MODULE_NOT_FOUND` and `require.resolve` instead.
**Note**: this change only effect users using `@angular-devkit/core` public API and not application developers.
Removal changes were previously being improperly recorded with the wrong parent. A property can now be directly removed by setting the value to undefined or by using the delete operator.
BREAKING CHANGE:
The experimental workspace API has been removed from `@angular-devkit/core`. This API was no longer used by the Angular CLI and was replaced with the stable workspace API also found within `@angular-devkit/core`. This change does not affect project code and is related to tooling infrastructure only.
Most of the problems here come from return-only generics. A greater redesign of these core types is necessary to properly fix all the typing issues. However, all these types seem to be exported publicly. In the interest of not introducing any breaking changes, most of these fixes were just casting types to `unknown` or replacing generics with the maximally-allowed type (`JsonValue`).
