The repository contains CI check for rust 1.75 compatibility, but this check verifies that zenoh-c compiles with rust 1.75 with synchronized Cargo.lock.
This update adds dependency on pinned rust 1.75 compatible dependencies of zenoh which ensures rust 1.75 compatibility without cargo.lock.
So it's necessary to either:

• decide that we don't care about zenoh-c rust 1.75 compatibiliity by itself, Cargo.lock imposed compatibility is enough. In this case this PR can be abandonned
• decide that we want to make sure that zenoh-c works with rust 1.75 without cargo.lock. In this case test for build without cargo.lock must be added to PR
