remove otterscan_api_truncate_input function

[mattsse]

Describe the feature

This was a hack to truncate the input for otterscan responses

reth/crates/rpc/rpc-types-compat/src/transaction.rs

Line 48 in 726f5d8

fn otterscan_api_truncate_input(tx: &mut Self::Transaction);

with alloy-rs/alloy#2525 this is now natively supported in serde so we can remove this after the next alloy bump entirely

TODO

• after alloy bump, remove this trait function and usage

Additional context

No response
