ci: restructure build pipeline for dual deployment (#32)

* ci: restructure build pipeline for dual deployment

Replace withastro/action with explicit steps so the workflow produces
both a GitHub Pages artifact and a generic dist/ artifact. Adds
pull_request trigger for future preview support. GitHub Pages deploy
is conditioned on push to main so PRs don't trigger deployment.

Closes chinmina-docs-7yn.1

* ci: fix corepack enable and update action versions

Replace non-existent enable-corepack input on setup-node with an
explicit corepack enable run step. Update actions to latest versions:
setup-node v6, upload-pages-artifact v4, upload-artifact v7,
deploy-pages v5.

* ci: update checkout to v6

* ci: replace .mise.toml with .tool-versions for node version

Switch from mise.toml to the asdf-compatible .tool-versions file so
both mise and actions/setup-node (via node-version-file) read the
node version from a single authoritative source.
