disabling migration as it takes too long during installs

General MR

Summary

The BB Pipeline is failing when all-packages is enabled: https://repo1.dso.mil/big-bang/bigbang/-/pipelines/2466304 The BB pipeline will pass when only fortify is enabled: https://repo1.dso.mil/big-bang/bigbang/-/pipelines/2470195

This is due to the fortify_autoconfig setting migration.enabled: true as the process is memory and CPU intensive, time to do the migration when all packages are enables takes longer. The options would be increase the timeout much long, increase resources, or disable the migration:

fortify_autoconfig: |
    ...
    dbMigrationProperties:
      migration.enabled: false
