AbstractProvider interface has incorrect signature(s)

[janeklb]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The callback parameter of the sendAsync method (and maybe the send method too) returns a promise (not sure if this is always the case.. but it returns a promise sometimes). The implementation does not have a void signature.

https://github.com/ChainSafe/web3.js/blob/0b890b70b977451836dc693614960256bcbcb6d8/packages/web3-core/types/index.d.ts#L444-L449

Expected Behavior

The AbstractProvider interface should be updated so that the callback parameter of sendAsync and send is correct.

callback's return type should either be unknown or Promise<unknown> depending on whether promises are always returned.
