chore: undo pins for ntex crates (#2272)

ntex crates are a dependency of zenoh-plugin-mqtt and due to a
misunderstanding on how to use the zenoh-pinned-deps-1-75 I ended up
adding them here. The correct process is to pin them directly in
zenoh-plugin-mqtt Cargo.toml

To summarize I quote @milyin:
 - zenoh itself doesn't have locks, it can be used freely, it doesn't break user's projects by dependency locks
 - zenoh-pinned-deps-1-75 guarantees that zenoh is buildable with 1.75
 - plugins are not supposed to be used as dependencies, so they can contain needed locks right it their cargo.toml's
