fix ci: bump ahash dep and add bitcoind macos arm64 binary hash

[edouardparis]

• bump ahash dependency to fix macos build
• ci requires now macos aarch64 for the liana-gui tests on macos, sha256sum is added for bitcoind-26.1-arm64-apple-darwin.tar.gz (https://bitcoincore.org/bin/bitcoin-core-26.1/)

context?

[darosior]

Ok here is the context: tkaitchuck/aHash#195 and tkaitchuck/aHash#207.

[darosior]

However what's the issue with the GUI unit test here? It seems unrelated to this PR.

It seems that rust nightly on macos does not understand anymore this code:

#[cfg(all(target_os = "macos", target_arch = "x86_64"))]
pub const SHA256SUM: &str = "acb50edd20692a9d023de12da573b64ca0fd9b4e9a2b88d1251020a3022b0f27";

#[cfg(all(target_os = "linux", target_arch = "x86_64"))]
pub const SHA256SUM: &str = "a5b7d206384a8100058d3f2e2f02123a8e49e83f523499e70e86e121a4897d5b";

#[cfg(all(target_os = "windows", target_arch = "x86_64"))]
pub const SHA256SUM: &str = "7bd0849e47472aeff99a0ea2c0cefd98f5be829e5a2d3b0168b5a54456cc638a";

And find no SHA256SUM const. I have no way to fix it for now. Maybe something with the target_arch
