chore: Make Python 3.14 support official (#474)

* Add 3.14 to the matrix of tested python versions in tests.yml
* Run build-deploy-docs.yml, release.yml, tests.yml:build-doc and tests.yml:mypy on 3.14
* Say torchjd is compatible with 3.14 in installation.md and add 3.14 classifier in pyproject.toml
* Suggest 3.14 in CONTRIBUTING.md
* Add changelog entry
