ci(forgejo): drop setup-dotnet/setup-node/pnpm actions on Forgejo

code.forgejo.org does not mirror actions/setup-dotnet — the Forgejo
runner was failing at 'workflow prepared' with 'Unauthorized' trying
to clone it. Rather than fork a bunch of actions, install the tooling
directly on the runner host (apt dotnet-sdk-8.0, nodesource node 20,
npm -g pnpm) and call dotnet/node/pnpm inline. This keeps CI fully
independent from external action registries.

GitHub Actions copy in .github/workflows still uses the stock actions
(and the cloud-backed setup-dotnet); it will be disabled in a follow-up
once the Forgejo run is green end-to-end.
