GitHub Pages now uses Actions by default

> Do builds and deployments of private and internal repositories use GitHub Actions minutes?

> Yes. Just like any regular workflow, building and deploying a GitHub Pages site on a private or internal repository consumes GitHub Actions minutes. All GitHub accounts and organizations come with a generous amount of GitHub Actions minutes included for private repositories, and public repositories have unlimited actions minutes.

And according to [0]:

  | Plan        | Storage | Minutes (per month) |
  | GitHub Free | 500 MB  | 2,000               |

AFAIU Pages will not be free anymore, but with free "generous" limits instead.
