Someplace in foundry it seems to not populate the
key value correctly in the compiler storage layout type.
Unclear why its not always populated, it is in some cases
but not all. It could be anywhere between solc, foundry and
the foundry hardhat plugin.

The information is still there, it just needs to be parsed
from a different field. This PR uses a regex to parse the value
to pull it out. It recursively calls itself and we can be sure
that it will not infinitely recurse because a non empty string
is passed in the second time.

With this PR, I am able to successfully build the L2 genesis
state.
