Rename Tool Header and Filter Name to Report Type on Group Level

This issue is part of #503371 (closed)

Why are we doing this work

For #503371 (closed), we've already renamed the Tool header column at the Project level. In this issue, we'll make the same update at the Group level. Unlike the Project level, where the change had to be applied across three different pages, at the Group level, it only needs to be updated on the Vulnerability Page.

Additionally, we'll rename the Tool filter to Report Type.

These updates should be controlled by the vulnerability_report_type_scanner_filter feature flag, which currently exists only at the Project level. As part of this MR, we'll also ensure the feature flag is added at the Group level.
