fix pymongo.patch for more pymongo versions

[XenoAmess]

(tested on 4.3.3, 4.10.1)

reason:

1. the original patch compares too many lines, thus quite some pymongo versions actually failed the patch examination, thus we reduce it into a one liner. well according to history, this line nearlly always unchanged, and seems no reason for anyone to add another same line in anyway.
2. since pymongo 4.8 they move things in setup.py to _setup.py, thus the patch shall suite too.

Thank you for the contribution, I'll look into merging it shortly.

I'm still not quite clear for sereral things.

1. should we split it according to versions? (like I did in the second commit)
2. is there a version range mechanism in these patch files? like for [4.8,) or something. or the version 4.8 means it be already would cover 4.8+
3. is there some way to let it work in graalvm+mavenplugin+python-resources dependency toolchains?
   I modified the jar resources and made a local install and changed the dependency version in pom, and sadly to see it failed, but graalpy release can success(by modify the patch file in that folder.)

I know question 3 can be resolved by manually modify files generated at /target/classes/org.graalvm.python.vfs/home/lib-graalpython/patches, then clean pip-graal wheel caches, then rebuild.
but just think there shall be a...better way.

for question 2 I tried, but seems 4.8.0 cannot cover 4.10.1. maybe we have to suffer the patch failing error warning(though it can work)
or, if you want. I would write a small version range mechanism for this repo when weekend.

[msimacek]

Yes, splitting the versions would be better. The patches are not applied by the filename, but there's a metadata file with rules that determines what package version should be patched with which patch and the version can be a range. There is a README explaining the metadata format. The existing entry for pymongo doesn't specify a version, so it applies to all versions, but you can see other entries that have version ranges for inspiration. When you're done editing the metadata file, you can run python mx.graalpython/verify_patches.py graalpython/lib-graalpython/patches/ to check its syntax.

As for getting it into existing released jar, unfortunately there is no nice mechanism in the current release without repacking the jar manually. I think it's simpler to build the wheel outside of maven with pip wheel pymongo==4.3.3 and then put the wheel file path as a dependency (into <package> tag). In the next release there will be a way to override the patch directory with an env var and also a way for us to ship patch changes post-release (#429).
