Summary of Changes

This is just another attempt to fix the Joomla major.minor version not being reported in the nightly build notification after PR #47274 and the later commit 0630041 .

Drone seems to be tricky regarding expansion of environment variables, so this PR here replaces the "MINORVERSION" environment variable by directly using the "DRONE_BRANCH" variable with string operations described here: https://0-8-0.docs.drone.io/substitution/

Testing Instructions

Can not be easily tested without merging into 5.4-dev.

Actual result BEFORE applying this Pull Request

The Joomla major.minor version is not reported in the nightly build notifications, and the logs of the nightly_build steps in Drone don't show the value of the "MINORVERSION" environment variable.

Expected result AFTER applying this Pull Request

Hopefully it works now.
