BUG Mismatch in docs for Webhooks severity

[spencerschrock]

Describe the bug The YAML which defines the Webhooks check has a mismatch between the risk (high) and the description (critical). I'm not sure what the proper level is, but it affects what the users see in docs/checks.md and ultimately how the scores will be calculated once the Webhooks check is enabled.

Reproduction steps N/A

Expected behavior The risk and the description of the risk should match
