update supported python versions to 3.12-3.14

[korikuzma]

Feature description

We should support Python 3.12, 3.13, and 3.14 since 3.14 is now a supported version

Use case

We support most recent 3 Python releases; https://devguide.python.org/versions/

Acceptance Criteria

Given I am using the software templates
When I use the Python template in my project
Then my project must support the latest 3 stable Python versions (3.12-3.14)

Update MIN_PYTHON_VERSION to 3.12 .github/workflows/update-python.yaml

Potential Impact

We'll want to wait for bug fixes and deps to support 3.14 (at least when we update downstream repos)

https://github.com/GenomicMedLab/software-templates/blob/main/.github/workflows/update-python.yaml will run on the first of Jan. We may want to update the template before then?
