cabal.project: bump cardano-api pin to signed 11.2.0.0 commit

The release/cardano-api-11.2.0.0 branch was rebased to sign the
herald-bot commits with the IOHK key, producing a new SHA for the
tagged release commit. Point the source-repository-package pin at the
new signed SHA (3baa58e8cc) instead of the original (8b19d9161c) so
this branch tracks a reachable commit.
