build(deps): bump slackapi/slack-github-action from 2.1.1 to 3.0.1

[dependabot]

Bumps slackapi/slack-github-action from 2.1.1 to 3.0.1.

Release notes

Sourced from slackapi/slack-github-action's releases.

Slack GitHub Action v3.0.1

Breaking change: Node.js 24

This major version updates the minimum GitHub Actions runtime to Node.js 24. Most GitHub-hosted runners already include this, but self-hosted runners may need to be updated.

Run Slack CLI commands in your workflows

This release introduces a new technique for running Slack CLI commands directly in GitHub Actions workflows. Use slackapi/slack-github-action/cli@v3.0.1 to install the CLI and execute commands like deploy, manifest validate, and more.

Validate an app manifest on pull requests

Check that your app manifest is valid before merging changes:

- name: Validate the manifest
  uses: slackapi/slack-github-action/cli@v3.0.1
  with:
    command: "manifest validate --app ${{ vars.SLACK_APP_ID }}"
    token: ${{ secrets.SLACK_SERVICE_TOKEN }}

Deploy your app on push to main

Automate deployments whenever changes land on your main branch:

- name: Deploy the app
  uses: slackapi/slack-github-action/cli@v3.0.1
  with:
    command: "deploy --app ${{ vars.SLACK_APP_ID }} --force"
    token: ${{ secrets.SLACK_SERVICE_TOKEN }}

Any command available in the Slack CLI can be passed through the command input — just omit the slack prefix.

The token input accepts a service token for authentication. You can gather this token by running slack auth token with the Slack CLI and storing the value as a repository secret.
