Fixes: no tracking issue; CI on mainline is failing (example run: https://github.com/OpenJobDescription/openjd-cli/actions/runs/42106317837).

What was the problem/requirement? (What/Why)

ubuntu-latest now resolves to Ubuntu 26.04, which has no Python 3.9 for actions/setup-python ("The version '3.9' ... was not found for Ubuntu 26.04"). The 3.9 job fails and fail-fast cancels the rest of the matrix.

What was the solution? (How)

Drop 3.9 from the CI matrix in code_quality.yml, the same change aws-deadline/deadline-cloud-worker-agent made in #1130. The matrix lives in this repo's caller workflow, so no change to the shared reusable workflow is needed.

What is the impact of this change?

CI no longer tests Python 3.9. requires-python stays >=3.9; worker-agent #1130 also raised it to >=3.10, which is a separate maintainer decision for this package. Note: release_publish.yml also builds on Python 3.9 on ubuntu-latest, so the next release will hit the same error; left unchanged here.

How was this change tested?

actionlint passes on the changed workflow(s); this PR's own CI run is the functional test.

Was this change documented?

N/A, CI-only.

Is this a breaking change?

No.

Does this change impact security?

No.

Nit: Removing 3.9 from the matrix means no CI job runs on 3.9 on any OS, but pyproject.toml still has requires-python = ">=3.9" and the Python :: 3.9 classifier. Only ubuntu-latest lacks a 3.9 build; windows-latest and macos-latest can still run it. With nothing testing 3.9, a change that breaks 3.9 at runtime (e.g. stdlib APIs added in 3.10) would merge unnoticed and ship to 3.9 users.

You could keep 3.9 in the matrix and drop only the broken combination:

exclude:
  - os: ubuntu-latest
    python-version: '3.9'

The other option is to raise requires-python to 3.10 and remove the 3.9 classifier.
