Superseded by #1885, which includes this update in the consolidated dependency PR targeting paullizer-react-v2-ui. Closing this original PR to avoid keeping duplicate updates open until branch promotion. The replacement PR is still open; the updates will follow the V2 branch through Development to main after review and merge. This PR is being closed as superseded, not merged directly into main.

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.
