Rename "Enable SVG Badge support (unauthenticated)" checkbox to "Enable unauthenticated SVG badge access" as part of deprecation

[SaberStrat]

Current Behavior

Currently, the checkbox controls whether badges are disabled or enabled, but then only as an unauthenticated API.

Proposed Behavior

As the planned support of authentication and authorisation for the Badge API in DependencyTrack/dependency-track#3596 was changed from an immediate breaking change into a deprecation with a grace period before removal, the checkbox won't be removed (#985) during the grace period either.

Instead, as part of the first step of the deprecation, the checkbox shall let the user control whether unauthenticated and unauthorised access to badges is enabled or disabled. In both settings, the Badges API will remain accessible to authenticated and authorised requests--i.e. accessible to requests supplying an API key.
