fix: broken link EIP-7212 evm.rs (#136)

Hi! In this pull request, I fixed a broken link in the `evm.rs` file.
The old reference to `EIP-7212` was replaced with the correct link to
`RIP-7212`. Following
[EIP-7607](https://eips.ethereum.org/EIPS/eip-7607#considered-for-inclusion),
the link and label were updated to align with the correct RIP
specification.
