ci: run benchmark metadata steps on Python 3.12 (#1427)
### Rationale for this change
Every `benchmark` shard is failing at "Set up Python for benchmark
metadata":
```
##[error]The version '3.9' with architecture 'x64' was not found for Ubuntu
26.04.
```
`benchmark.yml` requests Python 3.9 on `ubuntu-latest`, which is moving
to Ubuntu 26.04; `actions/setup-python` has no 3.9 build for that image,
and 3.9 is end of life. This fails on `main` (e.g. run 40373053653) and
on any PR that runs the benchmark workflow, such as #1423.
### What changes are included in this PR?
Use Python 3.12 for both setup-python steps in `benchmark.yml`, matching
`lint.yml` and `test.yml`. Python is only used to install and run the
conbench `benchadapt` collector (`ci/scripts/bench_adapt.py`).
### Are these changes tested?
Locally on Python 3.12.13: the pinned `benchadapt` commit installs, and
`bench_adapt.py --capture-machine-info` writes the machine-info JSON for
a sample result file. `actionlint` accepts the workflow. This PR's own
benchmark run exercises the change on CI.
### Are there any user-facing changes?
No.
