Cap Cython below 3.3 so the pyOpenMS build works again

[t0mdavid-m]

The Docker image build fails in the compile-openms stage at make -j4 pyopenms:

File ".../autowrap/PXDParser.py", line 69, in _check_type_constness
    return isinstance(ctype, Nodes.CConstTypeNode)
AttributeError: module 'Cython.Compiler.Nodes' has no attribute 'CConstTypeNode'
AttributeError: module 'Cython.Compiler.Nodes' has no attribute 'CConstOrVolatileTypeNode'
make: *** [Makefile:466: pyopenms] Error 2

autowrap is pinned to 0.24, whose constness check reflects on those two Cython nodes, while Cython had no upper bound and now resolves to 3.3.0, which removed the second one as well - so the fallback raises and the pyOpenMS code generation dies. Nothing in the repository changed; the same commit built fine before Cython 3.3 was released.

Change

Dockerfile:69 and Dockerfile.arm:62: 'Cython>=3.1' -> 'Cython>=3.1,<3.3', plus a comment explaining the cap.

Why <3.3

Checked against autowrap 0.24: Cython 3.1.8, 3.2.0 and 3.2.9 all still provide CConstOrVolatileTypeNode and take the fallback path; 3.3.0 does not. Lifting the cap again needs an autowrap that supports Cython 3.3 (0.27.0 is current), which in turn has to match the OpenMS branch the image builds.

Note

The image build on develop was already red before Cython broke it: the run for #96 died at Dockerfile:225, gh release download ... -p "OpenMS-App.zip" -> "no assets to download". Expect the build to get past make pyopenms and then hit that step unless a release asset exists now.
