GitHub Action that posts a message to a Slack channel

Optional The Slack auth token. This is only required if environment variable SLACK_BOT_TOKEN is not set.

Required The channel name to post to (example: #general)

Optional The timestamp ID of the parent message to reply to (e.g., the ts output from a previous Slack message call)

Required The message text to post. See Slack's documentation on formatting. Note that single quotes in your message must be escaped as \' due to how this input is consumed by bash.

Optional Whether links in the message should be unfurled (default: true)

The timestamp ID of the message (can be used to make subsequent Slack messages a threaded reply)
