fix(datasource/python-version): gracefully handles python.org 429 rate limiting When python.org returns HTTP 429, falls back to containerbase prebuild releases instead of aborting the entire repository with ExternalHostError.
This datasource returns Python releases from the python.org API.
It also fetches deprecated versions from the Endoflife Date datasource.
Because Renovate depends on containerbase/python-prebuild it will also fetch releases from the GitHub API.
Example custom manager
Below is a custom regex manager to update the Python versions in a Dockerfile.
Python versions sometimes drop the dot that separate the major and minor number: so 3.11 becomes 311.
The example below handles this case.
ARG PYTHON_VERSION=311
FROM image-python${PYTHON_VERSION}-builder:1.0.0
