Fix issues with Python 3.14 and add ARM wheel builds

[mattkjames7]

• Added Python 3.14 binary.
• Added ARM binaries for Linux.
• Fixed segmentation fault when handling datetimes in Python 3.14.
• Modified tests to handle new behaviour of sys.getrefcount() in Python 3.14.
• Moved Linux builds into manylinux container based on libc version 2.34 to allow binaries to run on a wider range of Linux distros.
• Simplified Linux build and test by:
  • building and testing all supported Python versions in the same job,
  • testing using the latest Memgraph Docker image,
  • removing the source distribution job (this now happens by default with the python -m build command).
• Added scripts to simplify building binaries on Linux manually.
• Build custom OpenSSL and zlib static binaries to link to the pymgclient binary in line with the versions used by Memgraph. NOTE: the manylinux container is based on AlmaLinux, which does not provide static libs; the dynamic library for OpenSSL is much more recent than what most other current distros use (3.5.1), so linking to that would mean that it would only work on hosts with the same version or newer.
• Added pyproject.toml (closes Add pyproject.toml #52)

But I can see build is passing so 😅

I randomly run this in a review since I was interested in the uv

All looks good, just have a question about why we need the isinstance stuff for Python 3.14.

Otherwise, I'm happy to approve.
