contracts-bedrock: omit build-info (#9115)

* contracts-bedrock: omit build-info

The `build-info` was required by the legacy hh deploy workflow.
It is no longer required and will save a lot of disk i/o by turning
off. `slither` uses build-info but it will clean and pass the cli
flag to `forge` directly. We do not need to create the build info
on each build. This should speed up foundry build times but not
by a huge amount.
