Fix the quimb backend following its CircuitBase refactor (backport #200) (#201)

* Fix the quimb backend following its CircuitBase refactor (#200)

* Fix the quimb backend following its CircuitBase refactor

This adds support for recent development versions of quimb while
maintaining compatibility with older versions.

Fixes #199.

* Add release note

* Remove redundant 'of quimb'

(cherry picked from commit f6c4437a2)

# Conflicts:
#	qiskit_addon_aqc_tensor/simulation/quimb/__init__.py

* Resolve backport conflicts for Python 3.9 compatibility

Mergify's backport of #200 left unresolved conflict markers because
`main` switched to `X | None` type annotations, which cannot be
evaluated at runtime by plum's `@dispatch` on Python 3.9 (still
supported on this release branch).

Resolve the conflicts by keeping the semantic change from #200 (the
`CircuitBase` return type) while retaining the release branch's
runtime-safe annotation style:

- `out_state` parameters keep `Optional[np.ndarray]`.
- `CircuitBase` is defined with an explicit `typing.Union[...]` rather
  than the `|` operator on plum `ModuleType` objects.

* Suppress guarded-import docs warning for CircuitBase

`CircuitBase` is imported inside a `TYPE_CHECKING` block but does not yet
exist in a released quimb, so sphinx-autodoc-typehints cannot import it
at doc-build time.  Under `sphinx-build -W` this guarded-import warning
fails the docs build.

Suppress just that warning subtype until quimb releases a version
containing `CircuitBase`, at which point the line can be removed.
