Remove _get_kwarg_value function (#13184)

Browse Source 
`_get_kwarg_value` function is useless, one can rely on python builtin
functionalities to do the exact same thing.

- **Description:** Removed `_get_kwarg_value`. Helps with code
readability.
  - **Issue:** the issue # it fixes (if applicable),
  - **Twitter handle:** @Guillem_96
