fix: Avoid problematic serde release

[lu-zero]

serde 1.0.172 and up rely on opaque non-reproducible binary blobs to function on certain targets, explicitly not providing a library-level opt-out.

This is problematic for some reasons, those that I consider more problematic:

• unauditable binary blobs are a security concern.
• the binary is produced cutting few corners (e.g. using a non-dropping allocator).

See serde-rs/serde#2538 for the full discussion.

We could close this just because with 1.0.184 the precompiled approach has been reverted.

Luckily we can :)
