devDependency cannot be updated

There is a devDep on {"@adobe/aio-cli-plugin-app": "^8.0.0"} however the current version is 9.2.0

I tried updating this, but immediately broke all the tests.

The way this is used it appears it could actually be a peer dependency. I think this need to be thought out and re-architected to work with published apis.

Calls to @adobe/aio-cli-plugin-app/src/commands/app/deploy are bound to break at any time, without even a major version bump, this is internal to the aio-cli-plugin-app and should not be directly depended on.

Start by reviewing the dependency on @adobe/aio-cli-plugin-app and the calls to @adobe/aio-cli-plugin-app/src/commands/app/deploy, then reproduce the test failures with version 9.2.0. The work is done when the plugin uses published APIs rather than internal paths and the test suite passes.
