Bump GitHub Actions to current majors

checkout, setup-node, upload-artifact and codecov-action to v7, pnpm/action-setup to v6 and action-gh-release to v3. All of them now run on the node24 actions runtime. No inputs changed for how the workflows use them. pnpm/action-setup v6 is also what makes trusted publishing work with pnpm 12.
