Change vulnerabilityFindingDismiss mutation to accept uuid argument

Why are we doing this work

We need to be able to dismiss pipeline findings. There is a mutation vulnerabilityFindingDismiss, but this does not work for pipelines. The only ID available to security findings is the UUID. We need to accept the UUID of a finding to dismiss the vulnerability finding and/or the security finding. We also need to deprecate the use of id as a parameter. However, that deprecation should come in a separate issue.

Non-functional requirements

• Documentation: Update GraphQL docs
• Testing: Add relevant tests

Implementation plan

• backend Add uuid as an input for the vulnerabilityFindingDismiss mutation
• backend Remove the requirement on id as an input
• backend Add check to make sure at least id or uuid is present

Verification steps

1. Run a pipeline on the main branch of a test project
2. Get the UUID of a finding via GraphQL

   query {
     project(fullPath:"jschafer/security-reports") {
       pipelines(first:1) {
         nodes {
           securityReportFindings(first:1) {
             nodes {
               uuid
             }
           }
         }
       }
     }
   }

3. Dismiss the finding via GraphQL

   mutation {
     vulnerabilityFindingDismiss(input:{uuid:"<uuid>"}){
       finding {
         title
       }
     }
   }

4. GraphQL should return with the title of the security finding
5. The Security tab on the pipeline should show the security finding as dismissed.
