Security API Automations model, has location field incorrectly marked as readOnly

The location field of the Automations model
https://github.com/Azure/azure-rest-api-specs/blob/c1c45178f4a761b48f1778ac46cdd3304d7e33ef/specification/security/resource-manager/Microsoft.Security/preview/2019-01-01-preview/automations.json#L319

Has a `Location` field which is referenced here
https://github.com/Azure/azure-rest-api-specs/blob/c1c45178f4a761b48f1778ac46cdd3304d7e33ef/specification/security/resource-manager/common/v1/types.json#L114

This is set to readOnly as true. This is a mistake, **this field is not read only** and is required by the API to be set when calling it on a create or update operation https://docs.microsoft.com/en-us/rest/api/securitycenter/automations/createorupdate

The downstream result of this is impacting the Go SDK for Azure making that package in the SDK non-functional, it always returns a 400 error `Code="LocationRequired" Message="The location property is required for this definition."`

See this issue https://github.com/Azure/azure-sdk-for-go/issues/12634

Start with automations.json around line 319 and the referenced common/v1/types.json definition around line 114, then compare the location metadata with the Security Automations create-or-update API documentation. Update the specification metadata and run the repository's relevant validation; done means location is accepted for create and update operations without producing the reported LocationRequired error.
