The `op-bindings` package has no tests in it, therefore
it doesn't need a job in CI. You can see in [this](https://app.circleci.com/pipelines/github/ethereum-optimism/optimism/54620/workflows/1ce56b22-29ac-46e8-9001-d419767756be/jobs/2361188)
job, there is nothing that runs.

`op-bindings` is deprecated and on its way out of the monorepo, services
are responsible for their own bindings management now.

The following see [here](https://github.com/ethereum-optimism/optimism/blob/9047beb54c66a5c572784efec8984f259302ec92/op-chain-ops/justfile)
for an example on how to generate bindings in a simple way.
