[Task]: Move updateSuperUser migration from repetitive migration strategy to bean creation strategy

[vivonk]

SubTasks

• Create beans for updateUserUser
• Coomunicate the same decision with the wider audience to adhere with this practice so that we dont' have to replicate these repeating migrations separately for MongoDB and Postgres. Rather single code works for both

[vivonk]

As discussed, we are not much interested in moving repeating migrations as bean on release branch as it doesn't help much with code changes efforts required going forward so we are not going a head with this appraoch.
