Explicitly specify versions on some dependent crates to make project buildable without Cargo.lock (#2082)

* explicit base64ct, jsonschema, pest, thiserror

* fixed crate versions to make build work on 1.75

* add check without Cargo.loclk to ci

* test without Cargo.lock on rust 1.75 only

* fix for cargo machete check

* pinned deps crate attempt

* implicitly lock dependencies only when building in workspace

* unnecessary changes removed

* toml formatting fix

* crate named zenoh-pinned-deps-1-75

+# ⚠️ WARNING ⚠️
+
+This crate is intended for Zenoh's internal use.
+It is not guaranteed that the API will remain unchanged in any version, including patch updates.
+It is highly recommended to depend solely on the zenoh and zenoh-ext crates and to utilize their public APIs.
+
+This is empty crate which pins exact versions of dependent crates necessary to build zenoh with Rust 1.75.
