Fix Wrong Migration IDs for User Parameter Values Migration (#45120)

Per discussion in Slack, I made a mistake with the migration IDs as I wanted to backport to 50 but used 51 IDs.
This PR uses 50 IDs and places the migrations in the correct place.

Not sure if it's mergable in this state because Stats has run with the PR containing the incorrect migration IDs.
