Chore: bump waku-rlnv2-contract-repo commit (#3651)

* Bump commit for vendor wakurlnv2contract

* Update RLN registration proc for contract updates

* add option to runAnvil for state dump or load with optional contract deployment on setup

* Code clean up

* Upodate rln relay tests to use cached anvil state

* Minor updates to utils and new test for anvil state dump

* stopAnvil needs to wait for graceful shutdown

* configure runAnvil to use load state in other tests

* reduce ci timeout

* Allow for RunAnvil load state file to be compressed

* Fix linting

* Change return type of sendMintCall to Futre[void]

* Update naming of ci path for interop tests
