deduceCloudEnvironment doesn't add "cloud" in AppEngine

[TWiStErRob]

Expected Behavior

As documented:

The application is running in a Cloud environment (present for all other cloud platform types)
-- https://docs.micronaut.io/latest/guide/#:~:text=present%20for%20all%20other%20cloud%20platform%20types

Actual Behaviour

micronaut-core/inject/src/main/java/io/micronaut/context/env/DefaultEnvironment.java

Lines 742 to 747 in f3c28be

	// deduce GAE
	if (StringUtils.isNotEmpty(CachedEnvironment.getenv(GOOGLE_APPENGINE_ENVIRONMENT))) {
	environments.add(Environment.GAE);
	environments.add(Environment.GOOGLE_COMPUTE);
	deduceComputePlatform = false;
	}

(compare to branches above, and notice that each add CLOUD explicitly.)

Steps To Reproduce

I haven't tried, I just stumbled upon the code.

Confirmed not working in GAE:

Do you want to submit an PR?

No, because there are no tests for this as far as I found, therefore it should be in scope to add regression tests, which is not as trivial as adding the line I highlighted.
