fix: update to Knative 0.17 (#145)

Also adjusted some dependencies and overwrite version to align
transitive dependencies.

Not sure why buildpack uses such an older docker dependency but that
clases with the docker dependency that is introduced by knative-dev/test-infra
(which is a dependency of the knative direct dependencies)

If there is a way to exclude a transitive dependency like that on test-infra,
this could be the better way to achieve the same result.

The build now works on macOs natively which was not the case before.
