ci: fix chart version update failing when version already matches

PR #45 added fetch and sequentialthinking MCP sidecars to values.yaml
and the deployment template but missed updating values.schema.json.
The schema has additionalProperties: false on mcp.sidecars, causing
Helm upgrade to fail with validation errors.

Also adds resourceProfile to the schema as it was missing.
