text: Title: Refactor: pkg_resources will be deprecated, instead use importlib.resources
  Body: There are currently, many instances where we use `pkg_resources`, but it will be deprecated. Instead, let's use `importlib` as suggested.
  
  Remove it also from `requirements.txt`.
  
  This exists in many labeler files and tests. Replace all usages.
  
  
  Example from `dataprofiler/labelers/base_data_labeler.py`
  ```python
  # remove this
  import pkg_resources
  
  # instead use this (note that this is built-in
  import importlib
  ```
  
  ```python
  # replace this
  default_labeler_dir = pkg_resources.resource_filename("resources", "labelers")
  
  # with this
  default_labeler_dir = importlib.resources.files("resources").joinpath("labelers")
  ```
