Update github.com/nwaples/rardecode/v2 to 2.2.0

[devantler]

github.com/mholt/archives

Error: ../../../go/pkg/mod/github.com/mholt/archives@v0.1.3/rar.go:105:9: cannot use or (variable of type *rardecode.ReadCloser) as rarReader value in assignment: *rardecode.ReadCloser does not implement rarReader (missing method WriteTo)

v2.2.0 is not backwards compatible with v0.1.3, so dependabot fails to upgrade rardecode when using archives.
