Fix: Normalize version string in wheel.py

[SyedaAnshrahGillani]

This pull request addresses a TODO in prelude/python/tools/wheel.py to normalize the package version.

The WheelBuilder class was using the version string as-is, without any normalization. This could
lead to inconsistencies in the generated wheel metadata.

This change introduces a normalize_version function that canonicalizes the version string according
to a simplified subset of the PEP 440 standard. This ensures that the version in the METADATA file
is always in a consistent and predictable format.

Thanks for this! I think an incomplete implementation of the spec would be OK, but unfortunately this is incorrect, because this implementation replaces all separators with ., but that's not a valid normalization of pre-release separators.
Concretely, normalizing 1.1-a1 should result in 1.1a1 but this code produces 1.1.a1

There's an implementation of the spec in the packaging package, which we might be able to vendor.

packaging is not included in the python standard library and since python_wheel is built using a python_bootstrap_binary rule it does not have access to third-party dependencies
