[FEAT]: Make it so the `run-smoke-test` workflow has added coverage to run the smoke test on Java 25

[edburns]

Describe the need

Consider .github/workflows/run-smoke-test.yml.

This workflow imperatively causes the smoke test specified in .github/workflows/run-smoke-test.yml to be run, with several, ✅✅extremely important✅✅ overrides so that the test is appropriate in the context of a CI/CD test.

The assignee of this issue must make an additive change to .github/workflows/run-smoke-test.yml so that the JDK 25 Virtual Thread specific behavior is also smoke tested.

Here are some invariant high level guides to the assginee.

1. Existing job smoke-test must be renamed smoke-test-jdk-17.

2. Create a net-new job, smoke-test-jdk-25.

   1. This job is largely a copy/paste of smoke-test-jdk-17 but with the following changes.

      • Run with the Microsoft JDK 25. ❌❌NOT temurin❌❌.

      • Extremely important ✅✅additional✅✅ Critical override statements.

        • Tell the agent to heed the "comment/uncomment" instructions in the Quick Start section of the top level README that have the literal prefix "// JDK 25+:"

          • These changes will make the resultant CopilotSDK class exercise the Java 25 Virtual Thread code path.

        • Make it so these comment/uncomment changes happen before building the jar whose main is CopilotSDK.

The topic branch name for this work must include the issue number for this issue.
