feat(cli-integ): release @aws-cdk-testing/cli-integ (#912)

#905 intended to trigger a release for `@aws-cdk-testing/cli-integ`,
where it did not rely on the deprecated `cli-lib-alpha` module. because
it was marked as a chore, the release was skipped and the latest version
still runs the tests that were removed in #905. These tests are now
failing because they cannot find the right version of `cli-lib-alpha`.
By releasing a version of `@aws-cdk-testing/cli-integ`, we won't have to
worry about this anymore.

this PR is intended to trigger a release and nothing else.

 ### Running a test suite against binaries
 
-The test suites that run the "init tests" require actual packages staged in CodeArtifact repositories to run. This requires you to do a full build, then create a CodeArtifact repository in your own account, uploading the packages there, and then running the tests in a shell configured to have NPM, Pip, Maven etc look for those packages in CodeArtifact.
