Upgrade web3j 4.8.1 -> 4.9.0

I'm not upgrading to 4.9.1 because at the time of this commit, there is no 4.9.1 version of the Gradle plugin and I would prefer to keep both of them in sync. 4.9.0 is good enough because it upgrades the `jnr-unixsocket` dependency which carries the upgraded version of `jnr-posix` [fixing the CVE](hyperledger-web3j/web3j#1616) for which it is was excluded previously from Besu
