Add Python 3.13 support to Flytekit

[ndonyapour]

The current Flytekit project supports Python versions in the range >=3.11,<3.13, which is not compatible with the Python requirements of some of the dependencies we need to use. Would it be possible to add support for Python 3.13 in Flytekit?

It seems likely that Flytekit now supports Python 3.13. There are example projects in the Flyte SDK repository that specify Python 3.13 in their .python-version files, suggesting compatibility with this version—for instance, see this example and another here.

However, the official user guide for installing development tools only explicitly mentions support for Python 3.8 and higher, without specifically listing 3.13, so there may be some lag in documentation updates (source). Would you like more detail on how to verify or use Python 3.13 with Flytekit?

The Python requirement in Flytekit explicitly specifies the range >=3.11,<3.13, as shown here:
