Update GitHub Actions and README

[Yer1k]

In this PR, the following items are updated:

1. Updated .github/workflows/gh-pages.yml:

   • actions/checkout from v3 to v4
   • actions/cache from v3 to v4
   • actions/setup-node from v3 to v4 with node-version from 18 to 20
   • actions/upload-pages-artifact from v1 to v2
     • Note: v3 and v4 are incompatible with actions/upload-artifact@v3, which currently do not support on GHES
   • actions/deploy-pages from v1 to v3

2. Updated .github/workflows/run_data_sync.yml:

   • actions/checkout from v3 to v4
   • actions/setup-python from v4 to v5
   • actions/cache from v3 to v4

3. Updated README:

   • Updated Yer1k's running page link
   • Added instructions for people who would like to deploy their running page on GitHub.io with custom domain to avoid potential artifact index issues

PS: I have tested the changes on my own repo, and they all worked as expected; however we would still get annotations/warnings on GitHub Actions due to "Node.js 16 actions are deprecated", which is caused by pnpm/action-setup@v2 and actions/upload-artifact@v3. As for the former, other people have started PRs on that project, trying to fix the Node issue, yet it has not been updated. Then for the latter one, as mentioned in list 1, even though the Node issue has been fixed, due to GHES incompatibility, we currently cannot update the upload-artifact version. Please feel free to let me know if anything needs to be changed before the merge. Cheers!
