Python 3.14 build

[0x78f1935]

• Bumped CONNECTOR_VERSION to the latest version 3.4.1 -> 3.4.7
• Bumped Django version to the latest version 4.2.16 -> 5.2.7
• Added Python 3.14 in matrix strategy

I did not intend to change " to ' in certain cases but my IDE insisted.

Why this PR?

I've decided to upgrade my Django stack from Python 3.13.3 to 3.14.0 and this package is one of those packages which have not been updated yet to support Python 3.14.0.

ERROR: Failed building wheel for mysqlclient Failed to build mysqlclient 

Solution?

I've compiled mysqlclient.whl for my windows system running Python 3.14.0, Django 5.2.7 and MariaDB C Connector 3.4.7
dist.zip and it works.

I've bumped versions in the CI/CD Pipeline in the hopes the pip issue will resolve once the correct build for the mysqlclient wheel package is available on pip. However, it seems to me that the Pipeline is not responsible for publishing to PyPi.

Even while downgrading back to the default "LTS" tests, the tests fail. But 5.2.7 should be LTS, so those tests are outdated? I don't know

Yesterday I did the same - build my own whl. i've created #770, because i don't seen you pull request before, sorry.
