template function "humanizeNoSmallPrefix" is not recognize with promTool 2.7.1

Bug Report

What did you do?
I have the following alert rule that use the template function "humanizeNoSmallPrefix"

  - alert: AlertExample
    expr: vector(1) == 1
    for: 1m
    annotations:
      description: '{{ $value | humanizeNoSmallPrefix }} > 0 for last minute'

And the promTool 2.7.1 says it doesn't know the function humanizeNoSmallPrefix. It works using promTool 2.5.0

What did you expect to see?
I expected that promTool was ok with this rule

What did you see instead? Under which circumstances?
Running promTool 2.7.1, it returns the following error:

"AlertExample": msg=template: __alert_AlertExample:1: function "humanizeNoSmallPrefix" not defined

That never worked, that's a template (not a function) defined in the console templates library example, which aren't available to rules.

Indeed, after deep verification, this particular alert was not checked.

sorry for the inconvenience
