Incorrect definition for Microsoft.Web/sites/functions/keys resource body

The PUT schema references "KeyInfo" directly as the PUT body:
https://github.com/Azure/azure-rest-api-specs/blob/cde7f150e8d3bf3af2418cc347cae0fb2baed6a7/specification/web/resource-manager/Microsoft.Web/stable/2020-12-01/WebApps.json#L3801

KeyInfo is defined here:
https://github.com/Azure/azure-rest-api-specs/blob/cde7f150e8d3bf3af2418cc347cae0fb2baed6a7/specification/web/resource-manager/Microsoft.Web/stable/2020-12-01/WebApps.json#L23121-L23134

Instead, the expectation is that the body should be an ARM resource schema, with "properties" of type "KeyInfo".

This is resulting in incorrect Bicep types & incorrect ARM template schema documentation being generated.

These two comments appear to confirm the service behavior:
https://github.com/Azure/azure-quickstart-templates/issues/6757#issuecomment-582008031
https://github.com/Azure/bicep/issues/784#issuecomment-906402741

Open specification/web/resource-manager/Microsoft.Web/stable/2020-12-01/WebApps.json at the PUT schema around line 3801 and compare it with the KeyInfo definition around lines 23121-23134. Confirm the body follows the ARM resource shape with properties typed as KeyInfo, then verify that the resulting Bicep types and ARM template schema documentation describe that shape correctly.
