TECH_DEBT: Add QA2 environment support to get_deployed_commit.py

The Deploy_All_Services pipeline has offered scale-qa2 as an environment since
82f073a, but get_deployed_commit.py only recognized dev-scale, scale-test and
scale-qa. Selecting QA2 failed the Summarize job with "Unknown environment
'scale-qa2'", which skipped the dependent Deploy job.

- Map scale-qa2 to a QA2_BASE_URL environment variable, alongside the existing three
- List scale-qa2 in the unknown-environment and empty-BASE_URL error messages
- Document scale-qa2 in the script docstring and the Scripts/README.md row
- Mention QA2 in the pipeline's environment parameter displayName

Verified by running the script against scale-qa2 with QA2_BASE_URL set to
https://qa2-admin.nhsnlink.org, which resolved the deployed commit 78b98b4 from
/api/info. Unknown environments and the direct https:// URL argument are unchanged.

Requires a QA2_BASE_URL variable to be added in Azure DevOps wherever QA_BASE_URL is
already defined; without it the script reports the empty-BASE_URL error rather than
querying the wrong host.
