text: Title: slowapi uses limits==2.8.0 which contains usage of deprecated pkg_resources
  Body: **Describe the bug**
  
  Our application uses `slowapi==0.1.7` which makes use of `limits==2.8.0`
  
  The problem is `limits==2.8.0` uses `pkg_resources` which is deprecated and when we run tests they fail with:
  
  ```python
  src/common/limiter.py:1: in <module>
      from slowapi.extension import Limiter
  .nox/test-3-10-item/lib/python3.10/site-packages/slowapi/__init__.py:1: in <module>
      from .extension import Limiter, _rate_limit_exceeded_handler
  .nox/test-3-10-item/lib/python3.10/site-packages/slowapi/extension.py:25: in <module>
      from limits import RateLimitItem  # type: ignore
  .nox/test-3-10-item/lib/python3.10/site-packages/limits/__init__.py:5: in <module>
      from . import _version, aio, storage, strategies
  .nox/test-3-10-item/lib/python3.10/site-packages/limits/aio/__init__.py:1: in <module>
      from . import storage, strategies
  .nox/test-3-10-item/lib/python3.10/site-packages/limits/aio/storage/__init__.py:6: in <module>
      from .base import MovingWindowSupport, Storage
  .nox/test-3-10-item/lib/python3.10/site-packages/limits/aio/storage/base.py:5: in <module>
      from limits.storage.registry import StorageRegistry
  .nox/test-3-10-item/lib/python3.10/site-packages/limits/storage/__init__.py:12: in <module>
      from .base import MovingWindowSupport, Storage
  .nox/test-3-10-item/lib/python3.10/site-packages/limits/storage/base.py:6: in <module>
      from limits.util import LazyDependency
  .nox/test-3-10-item/lib/python3.10/site-packages/limits/util.py:11: in <module>
      import pkg_resources
  .nox/test-3-10-item/lib/python3.10/site-packages/pkg_resources/__init__.py:121: in <module>
      warnings.warn("pkg_resources is deprecated as an API", DeprecationWarning)
  E   DeprecationWarning: pkg_resources is deprecated as an API
  ```
  
  I tried to manually edit `.nox/test-3-10-item/lib/python3.10/site-packages/limits/util.py` and apply the fix (Remove deprecated use of pkg_resources and switch to importlib_resource) and we don't get the warning anymore.
  
  **To Reproduce**
  
  On Python 3.10 we get this warning when running tests through nox
  
  **Expected behavior**
  
  `limits` fixed the issue in 3.3.0 https://github.com/alisaifee/limits/blob/master/HISTORY.rst#v330
  
  `slowapi` should use a more updated version of `limits`
  
  **Screenshots**
  
  (none)
  
  **Your app (please complete the following information):**
  
  Deps used:
  
  ```python
  fastapi==0.95.0
  limits==2.8.0
  slowapi==0.1.7
  ```
  
  **Python**: Python 3.10.9
  
  **Additional context**
  
  The best would be if `slowapi` could move to `limits>=3.3.0` so this problem would be solved.
  
  In alternative, a way to suppress `E   DeprecationWarning: pkg_resources is deprecated as an API` could work as well.
  Please note that this error is not happening on all our devs machines so I suspect other people may have some particular setting which is suppressing these warnings. The problem is that we can't find what it is.
  
  Thanks
