I am waiting for reviews. I think it's done from my side. Working correctly.

ah this is now a cheat that only works with CANCUN, hence the failing test.

so what we need now is a test, just like:

https://github.com/foundry-rs/foundry/blob/master/crates/forge/tests/it/cheats.rs#L10-L26

but uses

https://github.com/foundry-rs/foundry/blob/master/crates/forge/tests/it/test_helpers.rs#L273-L275

and we need a cancun/cheats folder not default/cheats

TODO

• create cancun/cheats folder and move test
• add a new rust test similar to cheats that uses the TEST_DATA_CANCUN config

hey @mattsse! I moved the test into cancun folder and ci is passing but struggling with the test.
