Some PEP440 versions appear to not be supported

What would you like help with?

I think I found a bug

How are you running Renovate?

Mend Renovate hosted app on github.com

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

No response

Please tell us more about your question or problem

The OpenTelemetry project publishes their packages using PEP440 as a versioning scheme. Most of these versions also happen to follow semver -- <major>.<minor>.<patchlevel> -- but some of them follow a PEP440-specific "pre-release" format: <major>.<minor>b0

It seems that Renovate does not properly parse these pre-release versions, thus is unable to identify these versions nor identify any potential updates.

To illustrate this issue, I've put up a minimal reproduction.
