Exclude examples from pnpm-workspace

[anbraten]

To speed up pnpm install in CI & docker builds I would suggest to maybe remove examples/* from the pnpm-workspaces.yaml config. This way the examples would also be more self-contained.

I'm not sure if this is something we want to do, because of

• Integration tests for examples #566

We could run a pnpm install inside each example when running integration tests but that might be slower than just installing them in one go.

What's your opinion on this?

Maybe a separate pnpm workspace with its own lockfile in the example folder could do the trick
