Hypothesis for Python - version 6.71.0

This release adds "GitHubArtifactDatabase", a new database backend
that allows developers to access the examples found by a Github
Actions CI job. This is particularly useful for workflows that involve
continuous fuzzing, like HypoFuzz.

Thanks to Agustín Covarrubias for this feature!
