RFR: 8341285: Clarify LocaleServiceProvider deployment on application module path

Tue Oct 1 17:34:46 UTC 2024

Please review this PR and [CSR](https://bugs.openjdk.org/browse/JDK-8341285) which clarifies that a Locale sensitive service provider can be deployed as a module.

This mainly follows the same format as the work done for [JDK-8340404](https://bugs.openjdk.org/browse/JDK-8340404), by providing a brief example, and pointing to the Deploying Service Providers section under ServiceLoader.

There is no test added, since there already exists java.text tests that deploy SPIs as a module.
