revert chunk circuit vk to mainnet version (#1361)

* add trace jsons to testdata

* update mainnet fork height; remove version field in trace

* v0.11.2

* fix l1 msg + 1559

* pick some changes from develop

* env var SCROLL_MAINNET_CURIE_BLOCK

* fix: table kind should not change over the fse code trailing bits

* #[serde(default)] for prestate

* update mainnet curie block to 7096836

* update l2geth

* add vk checking test

* add vk checking test

* exclude Bernoulli from FixedTable

* Revert "add error mcopy test  (#1332)"

This reverts commit 00cd3e0.

* try align with develop

* enable vk check

* Update test.rs
