e2e: use --broadcast with forge create (#281)

Forge started to require the `--broadcast` flag for actually deploying a
contract. Otherwise it will only do a dry-run.

We should really pin our foundry version. But let's wait until we rebase
to the latest upstream, since there have been changes to the overall
setup.

Closes #278
