Prepares for adding in L2 deployment scripts by adding
a `l1` tag to the deploy scripts that should run on L1.
Also add the tag flag to the deployment that happens
in CI. The L2 contract deployments will be added in
another commit. It is not a problem if the L2 contracts
are deployed to L1 in a testing environment but using
tags to save time and gas should be done. Also lints
a few lines of code where awaits are nested, nested
awaits are difficult to read.
