Move schema upgrade file to the right directory

[meaksh]

What does this PR change?

We just noticed that the schema migration file that was introduced here: #9065, is probably not in the right place.

It was added to susemanager-schema-5.0.8-to-susemanager-schema-5.0.9/ while at the time of merging the PR there was already a newer directory: susemanager-schema-5.0.10-to-susemanager-schema-5.0.11/

Probably during one of the latest rebases of the PR, a new directory of the schema migration was created and went unnoticed, so actually, the mentioned schema migration file would need to go there.

Still not new enough. Current version is already 5.0.10.
So to perform the migration again you need to put it into 5.0.10-to-5.0.11
