chore(deps-dev): Bump pyproject-hooks from 1.2.0 to 1.3.3 in /backend

[dependabot]

Bumps pyproject-hooks from 1.2.0 to 1.3.3.

Changelog

Sourced from pyproject-hooks's changelog.

v1.3.3

• No code changes from 1.3. The git tags and the version number got out of sync while fixing an issue with the Github actions workflow to publish the release. 1.3.3 exists only to get them back in sync without reassigning any tags.

v1.3

• Python 3.8 or above is now required (:pr:214).
• UserWarnings from the backend are now captured and re-emitted in the frontend process as a new category BuildBackendWarning, so that frontends can control how they are shown to users (:pr:213).
• Show the traceback from the backend on a BackendUnavailable error (:pr:219).
• Fix the return type annotation for prepare_metadata_for_build_wheel (:pr:209).
• Fix removing the internal _in_process directory from sys.path where the install location includes a symlink (:pr:230).
• Use os.path.commonpath instead of the deprecated commonprefix to validate the location of in-tree backends.
• Fix in-tree backends in locations containing the path separator character - : on Posix platforms, ; on Windows (:pr:232).
• Fix finding distribution metadata with importlib.metadata in the backend when an in-tree backend is used (:pr:212).
• pyproject_hooks can be built from source using flit_core 4.x (:pr:233).
• Document that the hooks.subprocess_runner context manager API is not thread-safe (:pr:227`)

v1.2

• Improve interoperability with importlib.metadata, fixing a regression in setuptools compatibility in 1.1 (PR :pr:199).
• Clean up the _in_process directory inside the package from sys.path before imporing the backend (PR :pr:193).

v1.1

• Add type annotations to the public API.
• More careful handling of the backend-path key from pyproject.toml. Previous versions would load the backend and then check that it was loaded from the specified path; the new version only loads it from the specified path. The BackendInvalid exception is now a synonym for :exc:BackendUnavailable, and code should move to using the latter name.

v1.0
