contracts-bedrock: fix contracts flake in CI

Adds a `STRICT_DEPLOYMENT=false` env var to the CI
for the foundry tests. There is a race condition with it
reading files from disk. The deploy process needs to get config
from disk and when all of the foundry tests run in parallel,
sometimes particular tests will think the files do not
exist.

Ideally we can figure out a way to express to foundry "do something
only once" and then checkpoint the state, kind of like a meta `setUp`
but this doesn't seem to be possible, `setUp` is called many times.
