[FEATURE_REQUEST]: Allow for multiple custom checks at once

[Nicholas Moy]

Description of the problem/feature request
Allow for multiple custom checks at once. If utilizing multiple custom checks at once is already available, make it apparent in the documentation how to do it

Description of the existing behavior vs. expected behavior
Output of github action after attempting to do multiple checks below. It's clear in the docs how syntax is written for one custom check, but what's the best way to do multiple?

Run stackrox/kube-linter-action@v[1](https://github.com/edx/edx-internal/actions/runs/3315200215/jobs/5475477031#step:5:1).0.4

Error: Process completed with exit code 1.

Additional context
Custom checks block i'm trying out is currently written out as follows:

customChecks:
  - name: image-tags-block
    template: latest-tag
    params:
      BlockList: 
      - .*:(latest)$
      - ^[^:]*$
      - (.*/[^:]+)$
  - name: image-tags-allow
    template: latest-tag
    params:
      AllowList:
      - .*:(alpine)$
      - ^[^:]*$
      - (.*/[^:]+)$

if there's an alternative way to write them, please point it out.
