Update Dependabot config file

[dependabot-preview]

👋 Dependabot is moving natively into GitHub! This pull request updates your config file to the new syntax. When you merge this pull request, we'll swap out dependabot-preview (me) for a new dependabot app, and you'll be all set!

With this change, you'll now use the Dependabot page in GitHub, rather than the Dependabot dashboard, to monitor your version updates. Dependabot is now configured exclusively using config files.

Your previous schedule was set to live. This option is no longer supported in the new config file so it has been changed to daily.

You have configured automerging on this repository. There is no automerging support in GitHub-native Dependabot, so these settings will not be added to the new config file. Several 3rd-party GitHub Actions and bots can replicate the automerge feature.

If you've got any questions or feedback for us, please let us know by creating an issue in the dependabot/feedback repository.

Please note that regular @dependabot commands do not work on this pull request.
