The CSVFormat.Builder version of testEqualsSkipHeaderRecord was added without @Test when the builder was introduced (6a2376a), so it never ran. Its siblings, including testEqualsSkipHeaderRecord_Deprecated, all have @Test. This adds the annotation; the test passes, and the default mvn build passes.

Before you push a pull request, review this list:

• Read the contribution guidelines for this project.
• Read the ASF Generative Tooling Guidance if you use Artificial Intelligence (AI).
• I used AI to create any part of, or all of, this pull request. Which AI tool was used to create this pull request, and to what extent did it contribute? Claude (Anthropic) helped analyse the issue and draft the change and tests; I reviewed them against the code and ran the build.
• Run a successful build using the default Maven goal with mvn; that's mvn on the command line by itself.
• Write unit tests that match behavioral changes, where the tests fail if the changes to the runtime are not applied. This may not always be possible, but it is a best practice.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Each commit in the pull request should have a meaningful subject line and body. Note that a maintainer may squash commits during the merge process.
