Incorrect usage on zbctl evaluate decision --help

[korthout]

Describe the bug

The usage of evaluate decision through zbctl refers to processId or processKey but should instead refer to a decision.

$ zbctl.darwin evaluate decision --help
Evaluates a decision defined by the decision ID or decision key

Usage:
  zbctl evaluate decision <processId or processKey> [flags]

Flags:
  -h, --help               help for decision
      --variables string   Specify variables as JSON string (default "{}")

...

To Reproduce

• execute (in a shell) zbctl.darwin evaluate decision --help
• notice the usage referring to processId or processKey

Expected behavior

The usage should refer to a decision instead of a process.
