docs: update for probitas monorepo migration

The probitas project migrated from separate probitas-test/cli repo
to monorepo at probitas-test/probitas. Updated all references:

- Installation URLs from cli/main to probitas/main
- Nix flake input from probitas-test/cli to probitas-test/probitas
- Added GitHub Actions setup-probitas documentation

Also fixed Nix flake.nix to avoid name collision when using overlays.
The input name "probitas" shadowed the package name in lexical scope,
causing "with pkgs; probitas" to reference the flake input instead of
the overlay-provided package. Renamed input to "probitas-flake" to
resolve the conflict and enable overlay usage with "with pkgs;" syntax.

+### Using setup-probitas Action
+
+The recommended way to use Probitas in GitHub Actions:
+
+```yaml
+- uses: probitas-test/setup-probitas@v1
+  with:
+    version: latest # or specific version like '0.7.1'
+
+- name: Run scenarios
+  run: probitas run
+```
+
+See
+[probitas-test/setup-probitas](https://github.com/probitas-test/setup-probitas)
+for full documentation.
+
+### Using Nix in GitHub Actions
+
+For projects using Nix flakes with
+[nixbuild/nix-quick-install-action](https://github.com/nixbuild/nix-quick-install-action):
+
+```yaml
+- uses: nixbuild/nix-quick-install-action@v34
+
+- name: Run scenarios
+  run: nix run github:probitas-test/probitas -- run
+```
+
+Or within a Nix development shell:
