Size Label Customization

[bflad]

Description

Hi there! 👋 We would love the ability to customize the size labels that get applied. In our use case, it is to match previously existing capitalized labels (e.g. size/XS) and associated workflows with those.

Proposal

Add new configuration options with defaults matching the existing label names:

inputs:
  # ...
  xs_label:
    description: 'Label for xs PR'
    required: false
    default: 'size/xs'
  s_label:
    description: 'Label for s PR'
    required: false
    default: 'size/s'
  m_label:
    description: 'Label for m PR'
    required: false
    default: 'size/m'
  l_label:
    description: 'Label for l PR'
    required: false
    default: 'size/l'
# ...
runs:
  using: 'docker'
  image: 'Dockerfile'
  args:
    - ${{ inputs.GITHUB_TOKEN }}
    - ${{ inputs.xs_label }}
    - ${{ inputs.xs_max_size }}
    - ${{ inputs.s_label }}
    - ${{ inputs.s_max_size }}
    - ${{ inputs.m_label }}
    - ${{ inputs.m_max_size }}
    - ${{ inputs.l_label }}
    - ${{ inputs.l_max_size }}
    - ${{ inputs.fail_if_xl }}
    - ${{ inputs.message_if_xl }}
    - ${{ inputs.github_api_url }}

And adjusting hardcoded size/ references in the code.
