Merge rust-bitcoin/rust-bitcoin#3918: Remove deprecated `std::error::Error` trait method impls 

0719997fee api: Run just check-api (Tobin C. Harding)
1e503a8d3b Remove deprecated std::error::Error trait method impls (Tobin C. Harding)

Pull request description:

  The `description` method was deprecated in Rust `v1.42`. The `cause` method was deprecated in Rust `v1.33`. Our MSRV is now Rust `v1.63`.

  We do not need to implement the deprecated functions any longer.

  Fix: #3869
