Superseded by #4707

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.

@dependabot reopen

[dependabot]

Beginning January 27, 2026, Dependabot will no longer support the @dependabot reopen command. Please use GitHub's native pull request controls instead. Please see the changelog announcement for additional details.

Looks like sinatra is up-to-date now, so this is no longer needed.
