Description

With a task like the following:

version: '3'
tasks:
  deploy:
    cmds:
      - echo "deploying to {{.ENV}}"
    requires:
      vars:
        - name: ENV
          enum: [dev, beta, prod]

The following error will be shown when the required variable is missing:

task: Task "deploy" cancelled because it is missing required variables: ENV

When an enum is set like here, it would be great if the allowed values would be shown in the error. This way the user doesn't have to look into the Taskfile to see what values are allowed in situations where this isn't obvious.
