fix(@angular/cli): add schema.json options to parsed command, also …

…when a version is passed to `ng add <package>@<version>`

This commit fixes the method `AddCommandModule.getCollectionName()`, so it now returns only the package name, but remove the specified version (if present).

Previously, a `@<version>` specified in the const `collectionName` was causing a (silenced) error during the invocation of `workflow.engine.createCollection(collectionName)`, which lead to skipping eventually the invocation of the method `this.addSchemaOptionsToCommand()` in the try/catch block.

fixes #27766
