### Elasticsearch Version

### Installed Plugins

### Java Version

_bundled_

### OS Version

N/A

### Problem Description

@arteam [observed](https://github.com/elastic/elasticsearch/pull/83221/files#r795474431) that `static record` is redundant, records are apparently implicitly static. I think we should make sure that Checkstyle picks this up rather than needing human involvement.

### Steps to Reproduce

Mark a record declaration as `static` and observe that `./gradlew precommit` still passes.

### Logs (if relevant)
