Auto-update Anki dependency

[VikashKothary]

When a new version of the Anki dependency is released, we should automatically update this project and raise a PR.

This is a great idea! But how? And I encounter an anki module import error in version 2.1.46(although this may not happen frequently),This will make people cannot use it for long until PR applied.
And,sometimes,there is no need to update anki module ,because older module version may support latest Anki.
All in all,this will be convienent!

A scheduled github action could be used for that. At least that way it opens a PR with 24h delay at max.

Could this just be dependabot? https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/about-dependabot-version-updates
