fix(ci): delete examples before linting

In this workflow we only want to check generated code and don't want to
fail the build when waiters or examples do not match the generated code.
Examples often use waiters, so the `make sync-tidy` step in sdk-go would
fail when there are no waiters. Thus we also remove the examples before
linting.
