fix: allow dotfiles in page artifacts

[daniiiol]

🐛 Problem

e.g. Files under /static/.well-known/ were not served on GitHub Pages, even though:

• they exist in the repository (static/.well-known)
• Hugo correctly copies them to public/.well-known
• the site builds correctly locally

🔍 Root cause

The workflow used actions/upload-pages-artifact@v4, which internally excludes all dotfiles and dot-directories:

--exclude=".[^/]*"

As a result, public/.well-known was never included in the Pages artifact and therefore not deployed.

✅ Solution

The workflow was patched to create and upload the Pages artifact without excluding dotfiles, ensuring that .well-known is included in the deployed output.

No changes were required to Hugo configuration or project structure.

• feat: add "append-items" input actions/upload-pages-artifact#134

There's no indication that the 3.01 => 4.0 update provides any tangible benefit. In my view the dot file restriction introduced in v4 was designed and implemented in a bit of a rush.

I've subscribed to the issue and PR's above; perhaps they'll add a config param for this. In the interim, could we simply change our documentation to show V3 instead of V4?

That would also be a solution for me. In any case, the current situation is unfortunate and not immediately apparent to everyone.
