[sdk] Relax python_requires in setup.py

[AndersBennedsgaard]

Environment

• KFP version: 2.1.0 (not relevant)
• KFP SDK version: 2.7.0
• All dependencies version:

  kfp                      2.7.0
  kfp-pipeline-spec        0.3.0
  kfp-server-api           2.0.5
  

Steps to reproduce

I tried to install kfp using Poetry, where I've set the allowed Python versions to python = "^3.11.0". However, this results in an version solving failed error since 3.13.0 is allowed in that range, but isn't allowed by kfp:

pipelines/sdk/python/setup.py

Line 102 in c967d9f

python_requires='>=3.7.0,<3.13.0',

As new minor versions of Python should be backwards compatible, there is no real reason for setting an upper limit to the Python version to <3.13.0.

Expected result

poetry add kfp doesn't return an error, since python_requires='>=3.7.0' is used

As a workaround I can set kfp = { version = "^2.7.0", python = ">=3.7,<3.13.0" } to force Poetry to figure out the highest allowed Python version, but we shouldn't have to do this.
