Update cloud metadata sending invalid request body

[s-nel]

Readiness Checklist

• [ ] I am running the latest version
• [ ] I checked the documentation and found no answer
• [x] I checked to make sure that this issue has not already been filed
• [x] I am reporting the issue to the correct repository (for multi-repository projects)

Expected Behavior

SDK should send the correct request body without extra fields

Current Behavior

Update deployment metadata is sending field last_resource_plan_modified which is not part of the request schema.

Detected unexpected fields for [no.found.adminconsole.api.v1.routes.deployments.models.DeploymentUpdateRequest.DeploymentUpdateMetadata], not failing as strict deserialization has been disabled

io.circe.DecodingFailure$$anon$2: Unexpected field: [last_resource_plan_modified]; valid fields: system_owned, hidden, tags: DownField(metadata)

The request being made is to PUT /api/v1/deployments/{deployment_id} with user agent cloud-sdk-go/2.10.0
