Bug

Fixes: NuGet/Home#14665

Description

• Introduces Checkbox, "Use separate sources for vulnerability audit (?) help link"
  

  AuditSourceOptionsCheckbox.mp4
  • When Unchecked, it means there are no audit sources and reiterates that package sources are used for NuGet Audit.
  • When Checked, the Audit sources table is shown where audit sources can be configured.
  • The static message is now shown dynamically only when one or more audit source is in the table:

    Remove all audit sources to revert to using package sources for vulnerability data.

  

• Renames the VS Options page to "Sources" to be a more generic title for the screen representing package/audit/machine-wide sources.

• Creates headings (subcategories):

  • Package sources
    • (?) help link
  • Audit Sources
    • (?) help link. this section does not yet exist so it will open to the top of the page.
  • Machine-wide Package Sources
    • (?) help link
    • New description. Completed UX String review and we settled on a concise string:

    Machine‑wide package sources are provisioned by Visual Studio workloads and can only be enabled or disabled.
