None

Special notes for your reviewer:

Release note:

The `pkg/collections/maps` package now has a `ContainsKeysAndValues` function that checks whether a given map is a superset of another map, meaning all keys of the second map also exist in the first one and they have the same values. There is also a `ContainsKeysAndValuesFunc` function that allows to pass in a custom equality function for the value comparison and a `ContainsKeys` function that checks only for keys and ignores values.
