@aws-amplify/backend should inherit version bump of same kind from dependencies (#2042)

* refactor check_changeset_completeness with functions

* check backend version bump attempt 1 with temp workaround

* testing

* Revert "testing"

This reverts commit 65c6794.

* attempt 2 at checking changesets

* testing new attempt

* removed testing changesets

* testing

* testing changes

* testing

* removed unnecessary comments

* explictly add return type to modifiedPackages function

* added changeset types to dev dep

* altered logic of checkBackendDepVersion

* altered naming

* moved missing changesets check to function
