ci: update actions for Node 24

[leehack]

Summary

• Update GitHub-owned JavaScript actions to Node 24-compatible major versions.
• Update Codecov and native-sync PR creation actions to current major versions.
• Skip Codecov uploads for Dependabot PRs so dependency-only PRs do not fail when repository secrets are unavailable.
• Preserve hidden-file behavior for the Pages artifact upload after moving to actions/upload-pages-artifact@v5.

Test Plan

• go run github.com/rhysd/actionlint/cmd/actionlint@latest -color=false .github/workflows/*.yml
• git diff --check
• Verified bumped JS actions use Node 24 metadata: actions/checkout@v6, actions/setup-node@v6, actions/cache@v5, actions/configure-pages@v6, actions/deploy-pages@v5, peter-evans/create-pull-request@v8

Notes

• This should remove the GitHub Actions Node.js 20 deprecation warning for first-party JavaScript actions.
• Dependabot PR chore(deps): bump path-to-regexp from 0.1.12 to 0.1.13 in /website in the npm_and_yarn group across 1 directory #100 still needs a rebase/re-run or maintainer-applied equivalent after this lands.

CI / Review Evidence

• PR CI green on head e8018ce516e15e5e8da055b81d7bec3c086d6b27
• Verified latest run log no longer contains Node.js 20 actions are deprecated
• Addressed and resolved Copilot's Codecov condition comment by keying the skip to github.event.pull_request.user.login with a push-event guard

Pull request overview

Updates GitHub Actions workflow dependencies to Node 24-compatible major versions (primarily GitHub-owned JS actions), refreshes third-party actions, and adjusts CI behavior to avoid failing Dependabot PRs due to missing secrets.

Changes:

• Bumped GitHub-owned actions to newer major versions across workflows (e.g., actions/checkout, actions/setup-node, actions/cache, Pages actions).
• Updated third-party actions (codecov/codecov-action, peter-evans/create-pull-request) to current major versions.
• Added logic to skip Codecov uploads on Dependabot PRs and preserved hidden-file inclusion for Pages artifact uploads.
