Support rerunning builds that were never started due to concurrency limits

[Cadair]

This is a small extension to the fix for #6524.

It seems that you can't restart a build that didn't run due to concurrency limits:

(it never did retry in 5 minutes...)

• Read the Docs project URL: https://readthedocs.org/projects/sunpy/
• Build URL (if applicable): https://readthedocs.org/projects/sunpy/builds/16574795/

Hi! It does retry every 5 minutes. However, it may happen the concurrency limit is still reached but as the message does not change it's confusing (see #9011).

If after a long time it does not retry, it may be a bug, however. Can you please fill the template of the issue, providing your project URL and the build's URL as well?

Hi thanks for the info!

Have updated the post with URLS. In the case where it stops retrying it would be useful if there was a retry button.
