break(core): remove CircleCI env var fallbacks from the deploy command (AI-assisted) (#12714)

* break(core): remove CircleCI env var fallbacks from the deploy command (AI-assisted)

Remove the undocumented CircleCI-specific behaviors of `docusaurus deploy`,
inherited from the v1 `publish-gh-pages` script:

- `CIRCLE_PROJECT_USERNAME` fallback for the organization name
- `CIRCLE_PROJECT_REPONAME` fallback for the project name
- early exit when `CI_PULL_REQUEST` or `CIRCLE_PULL_REQUEST` is set
