Correct Per-Project New Issues Count in Release UI Components

This PR fixes the UI logic for displaying the new issues count (newGroups) per project in release-related components. It reverts a previous change that incorrectly referenced newGroups from the release object, restoring the correct access of newGroups from each project object within a release. The update ensures that metrics like new issues counts are accurately rendered in several areas of the frontend, improving the consistency of data shown per project in the releases UI.

Key Changes

• Updated newGroups reference from release.newGroups to release.projects[x].newGroups in all relevant components and mapping functions.
• Modified props in ReleaseCardProjectRow and its parent to correctly use the newGroups value from the project object.
• Fixed assignment of the error_count field in both useOrganizationReleases.tsx and releasesDrawerTable.tsx to use newGroups from the first project in a release.
• Removed obsolete direct propagation and destructuring of newGroups at the release level in affected UI files.

Affected Areas

• static/app/views/releases/list/releaseCard/releaseCardProjectRow.tsx
• static/app/views/insights/sessions/queries/useOrganizationReleases.tsx
• static/app/views/releases/drawer/releasesDrawerTable.tsx
• static/app/views/releases/list/releaseCard/index.tsx
