Subject: [PATCH] Fix Read the Docs stable branch update bug

Read the Docs fails to pick the latest version of the stable tag when
updated, i.e. a build is triggered but it takes the previous version.
This commit triggers a second build after 5 minutes to ensure that the
correct tag version is used for the documentation.

This is a known bug in RtD:
