This project handles dependency version bumps (including upstream changes from cloudflare-go) independently of the standard PR process using automation. This allows the dependency upgrades to land without causing merge conflicts in multiple branches and handled in a consistent way. The exception to this is security related dependency upgrades but they should be co-ordinated with the maintainer team privately.

Please remove the changes to the go.mod or go.sum files from this PR in order to proceed with review and merging.
