fix(ci): bump upload-pages-artifact v3 to v5 with include-hidden-files (#54)

Bumps upload-pages-artifact from v3 (56afc609) to v5 (fc324d35) and adds
required `include-hidden-files: true` parameter.

v5 defaults to excluding hidden files (breaking change from v3). Without
this flag, .nojekyll and other dotfiles would be silently dropped from
the Pages deploy.

Supersedes Dependabot PR #48 which bumps the action but doesn't add the
required parameter.
