Change Vulnerability Report to show Vulnerabilities with present_on_default_branch - rearrange indices
After #324857 (closed) and #324860 (closed) is merged we should make sure that the Vulnerability Report section under the Security & Compliance
tab doesn't show Vulnerabilites that are not present on the default branch
database create migration to re-arranged indices to account for present_on_default
branch.
This is a continuation MR from #324858 (closed). See this #324858 (comment 1031471856), looks like we need to revisit which indices need to be rearranged. Also all the indices are needed or not.
