The command help needs to make it specific you can add multiple apps separated by commas

[fernando-villalba]

Issue

The current help for the command doesn't tell you exactly how to add multiple applications, this is the example given:

...
Examples:
civo kubernetes application add NAME:PLAN --cluster CLUSTER_NAME
...

The user shouldn't need to guess you need multiple commas here.

Acceptance criteria

• Change the example to something like this:

...
Examples:
civo kubernetes application add APP1_NAME:PLAN,APP2_NAME --cluster CLUSTER_NAME
...
