name: Update PR label
description: >-
Add or remove a label on a pull request. Does nothing unless the pull
request is still open and still at the commit the result is for, so that a
result superseded by a push does not label/unlabel the work that replaced it.

token:
description: "Token to label with"
required: true
pr-number:
description: "Number of the pull request"
required: true
head-sha:
description: "Commit the result is for"
required: true
label:
description: "Label to set"
required: true
set:
description: "'true' to add the label, 'false' to remove it"
required: true
