Not sure why this is failing, elastic-package build doesn't show any updates locally.

[2022-03-02T20:07:27.205Z] README.md is outdated. Rebuild the package with 'elastic-package build'
[2022-03-02T20:07:27.205Z] Error: checking package failed: checking readme files are up-to-date failed: checking readme files are up-to-date failed
