Fixes #736

Summary

Raises timeout-minutes from 90 to 105 on the two jobs that run the full test suite with coverage (make test, which is pytest tests --cov=policyengine --cov-report=term-missing):

• .github/workflows/pr_code_changes.yaml, job Test (the "Test (3.11)" to "Test (3.14)" matrix)
• .github/workflows/push.yaml, job Test (pushes to main; its comment says it matches the pull-request Test job, so a release run isn't cancelled before Versioning)

Also adds changelog.d/736.changed.md and updates the comments above both limits.

Why

On Python 3.11 to 3.13, coverage.py 7.13.5 (from uv.lock) records coverage with its C trace function; it switches to sys.monitoring only on 3.14. Those jobs now take 65 to 90 minutes, and one of them is often cancelled at 90 minutes with no failing test:

PR	Cancelled at 90 min	Other 3.11-3.13 jobs	3.14
#730	3.12 (1h30m25s)	3.11 1h29m21s, 3.13 1h06m51s	58m49s
#735	3.11 (1h30m34s)	3.12 1h29m43s, 3.13 1h21m11s	47m22s

Left unchanged

• Other jobs in both workflows (changelog check, Lint, Mypy, Python-Compat, BundleVerification, Docs, Versioning, Publish, NotifyConsumers) do not run the test suite.
• pr_docs_changes.yaml (docs build, 30 min), draft-pdf.yml (paper, 15 min) and certify-uk-release.yaml (its jobs run their own checks with their own limits; it starts pr_code_changes.yaml with gh workflow run, so that run picks up the new limit).

Environment variables

This PR changes no environment variable, secret or variable reference. The two changed jobs read:

• HUGGING_FACE_TOKEN: repository secret (an organisation secret of the same name also exists), passed as secrets.HUGGING_FACE_TOKEN in the env: of the "Run tests with coverage" step, the only step that uses it, in both jobs.
• CI_RUNNER_X64 and CI_RUNNER_EVENTS: repository variables read in each job's runs-on expression. Neither is set at repository or organisation level, so both jobs run on ubuntu-latest.

Overlap

#731 sets both limits to 150 on its own branch. Whichever merges second will need its timeout-minutes values and comments reconciled.

Possible follow-up (not in this PR)

Measure coverage only on 3.14 and run plain pytest on 3.11 to 3.13. That would bring those jobs down to about the 3.14 time.

Checks run

• actionlint on both workflows: no new findings (one existing warning about actions/configure-pages@v3 in push.yaml, also on main).
• Parsed both workflows with PyYAML and confirmed both Test jobs have timeout-minutes: 105.
• make lint: passes.
• No tests run locally.
