index.html is rebuilt infinitely in watch mode, if it is right in the `outputPath` path

Command

build

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

14.2.1

Description

If index path in angular.json lies right under the outputPath (ex. index is public/index.html and outputPath is public), it will cause infinite rebuilding of index.html when the --watch option is used.

Probably caused by #23852.

Minimal Reproduction

1. Create a new workspace with ng new testapp with default settings.
2. Open testapp/angular.json and change the outputPath option to src.
3. Run cd testapp && ng build --watch --no-delete-output-path and wait for initial build to finish.
4. Observe the result.
