Change back to previous instruction

Why is this change being made?

This MR changes one of the MVP MR steps back to how it was prior to !124709 (merged)

Currently the added line suggests creating a second MR when both file updates should occur in the same MR. It also reverts to the mention of double checking the target branch as this MR is dependent on it for the release post process.
