[Release][C++] C++ Extra workflow for the `apache-arrow-24.0.0-rc0` was canceled

### Describe the bug, including details regarding any error messages, version, and platform.

C++ Extra includes the ODBC build and it will upload built ODBC artifacts when a tag is pushed:

https://github.com/apache/arrow/blob/4eca50770f7f2c5938a676f0719fbfc8aae4803c/.github/workflows/cpp_extra.yml#L735-L767

But the job for the `apache-arrow-24.0.0-rc0` was canceled:

https://github.com/apache/arrow/actions/runs/24404382907

Because the push to the `release-24.0.0-rc0` branch includes the same commit as the `apache-arrow-24.0.0-rc0` and we have `concurrency.group`:

https://github.com/apache/arrow/actions/runs/24404394663

https://github.com/apache/arrow/blob/4eca50770f7f2c5938a676f0719fbfc8aae4803c/.github/workflows/cpp_extra.yml#L77-L79

We don't want to cancel the job triggered by tag push. Can we improve the current `concurrency.group`?
