ci(e2e): Skip pnpm cache if skipping cypress run

When running the e2e action from a fork, we prevent multi-processing
in the E2E cypress tests skipping runs that aren't
matrix.container == 1.

However, this means that the pnpm cache folder isn't created, causing
the cache action to throw an error.

To fix this, we also skip building Node/cache setup step.
