build(deps): upgrade github.com/dgraph-io/badger to v4

Despite the major version bump, there are no breaking changes that
affects our existing code.

From changelog of BadgerDB 4.0.0:

  "This is a major release because we are making a switch to SemVer in
order to make it easier for the community to understand when breaking
API and data format changes are made."
