Master branch has a higher version than MOODLE_310_STABLE

I got an error during upgrade.
I'm upgrading Moodle 3.6 site with the latest local_datacleaner plugin (master branch) up to Moodle 3.11 with the latest local_datacleaner plugin (MOODLE_310_STABLE branch).

!!! Cannot downgrade local_datacleaner from 2021073000 to 2021051000. !!!
!! 
Error code: cannotdowngrade !!
!! Stack trace: * line 731 of /lib/upgradelib.php: downgrade_exception thrown

It seems like we need to restrain master version bumping up to the current date to make sure that MOODLE_310_STABLE is always higher than master version.
Increasing last digit of the master version would be fine.
