Fix #5007 Handle version str with extra info

[jenshnielsen]

Packaging 22 dropped LegacyVersion. We mostly handled this by converting any letters in the version str to a number using ord. However, the version str for keysight also contained extra info and looks something like this "A.02.17-02.40-02.17-00.52-04-01"

From packaging 22 and upwards this is an error. We fix that by splitting on - and only using the first part. The converter is only used for Keysight versions so adding it there seems safe.

This was not caught in the Keysight 34xxx driver tests since the test only runs for a simulated instrument that has the dig option marked installed and this path in the code is only taken if the dig option is not present in the options str.

Extend the tests for the converter to

• include this type of version field
• Ensure what comes out of the converter can be parsed by packaing.

• Add changelog
