refactor(iam): Adding new iam_policytroublershooter region tag - Migration process 1/2 for troubleshooter_java_dependency

[Kef131]

Description

Fixes b/385748009

This PR is the First part of the two PR process to rename the previous region tag, so it doesn't break the current devsite documentation. (Add new region tag -> Update devsite documentation -> New PR deleting old region tag)

The troubleshooter_java_dependency region tag belongs to the primary product of Policy Troubleshooter (part of Policy Intelligence).

The main reference to this region tag appears on the Google Cloud documentation at https://docs.cloud.google.com/policy-intelligence/docs/reference/libraries. It is documented under the Policy Troubleshooter API, which in all of the REST reference includes the .iam reference. Furthermore, in the google-cloud-java repository, it references the Policy Troubleshooter API to the IAM product (https://github.com/googleapis/google-cloud-java/tree/main/java-policy-troubleshooter) using the same dependency referenced on the main and first Google doc here.

Based on this, and considering the closest relation and use with IAM, the new prefix and name will be as follow

Region Tag Update

• Old Region Tag: troubleshooter_java_dependency
• New Region Tag: iam_policytroubleshooter_java_dependency

This includes the IAM product and adds the complete reference of the library on the region tag.

Impacted Documentation & References

1. Google Cloud Documentation: * Policy Intelligence Libraries
   • Policy Troubleshooter API (REST Reference under the .iam namespace)
2. GitHub Repository: * iam/api-client/pom.xml

Code Review

This pull request adds region tags around the google-cloud-policy-troubleshooter dependency in iam/api-client/pom.xml. The reviewer suggested updating the region tag name to include the iam_ prefix to align with the planned naming convention.
