CLI does not support deploying storage rules to multiple buckets

[m6keller]

[REQUIRED] Environment info

firebase-tools: 11.3.0

Platform: macOS

[REQUIRED] Test case

Deploy storage rules with firebase deploy --only storage with "firebase.json" containing the following:

"storage": [
		{
			"target": "main",
			"rules": "rules/storage.rules"
		}
	],

[REQUIRED] Steps to reproduce

Use the following directory structure:

- rules 
  - storage.rules 
- firebase.json
- .firebaserc

Run following with Firebase CLI to set target:

firebase target:apply storage main my-bucket.appspot.com

This adds the following to the ".firebaserc" file:

"storage": {
        "main": [
          "my-bucket.appspot.com"
        ]
      }

In firebase.json, include:

"storage": [
		{
			"target": "main",
			"rules": "rules/storage.rules"
		}
	],

Then, run firebase deploy --only storage

[REQUIRED] Expected behavior

After running firebase deploy --only storage, storage rules should deploy to Firebase console with following message:

✔  storage: released rules rules/storage.rules to firebase.storage 

✔  Deploy complete! 

[REQUIRED] Actual behavior

firebase deploy --only storage --debug
Terminal output:

Other notes:
Running firebase deploy --only storage with firebase.json including the following works as expected:

"storage": {
		"rules": "rules/storage.rules"
	}

Also:
Running firebase deploy --only storage:main gives the following error in the terminal:
Filters specified with colons (e.g. --only functions:func1,functions:func2) are only supported for functions, hosting, and firestore

This is said to be a valid command (where main is the name of a storage target) in the Firebase CLI Docs

Also can't use anymore in v11.3.0
firebase deploy --only storage:STORAGE_TARGET

Error is
Error: Filters specified with colons (e.g. --only functions:func1,functions:func2) are only supported for functions, hosting, and firestore

It is regression. And I think it's related to #4698

Had to downgrade to v11.1.0
