I am currently upgrading our chain to polkadot-v0.9.38 but when I run the build I get the following error:

error[E0405]: cannot find trait `Signature` in crate `signature`
   --> /home/albrayanov/.cargo/registry/src/github.com-1ecc6299db9ec823/ed25519-1.5.2/src/lib.rs:335:17
    |
335 | impl signature::Signature for Signature {
    |                 ^^^^^^^^^ not found in `signature`

Any ideas on how to resolve this since the signature::Signature implementation is not defined in our code (link to the branch can be found here)?
