feat: update L1 data fee in Curie hard fork (#755)

* update fee calculation

* add missing GPO slots to trace

* add placeholder for contract update logic

* nit

* update fee calculation

* update formula

* update GPO slots

* update L1GPO bytecode

* apply Curie in new worker

* move bytecode to config

* create an empty block for curie hard fork

* initialize L1GasPriceOracle storage slots

* add comments

* add test

* add IsCurie to traces and tests

* group GPO storage slots into a struct

* update unit test

* chore: auto version bump [bot]

* trigger ci

* update bytecode

* remove leading 0x

* update comments

* include rollup fee tests in CI
