Summary
Retry Markdown link checks when the endpoint responds with HTTP 429.
Background & Motivation
The http://reneefrench.blogspot.com/ site returns HTTP 429 frequently, leading to failed pre-commit checks when run in the Github Actions runners. The markdown-link-check tool supports retrying after an HTTP 429, automatically waiting until the time specified by the "retry-after" HTTP header. See the usage docs for details.
