pylint: Skip consider-using-f-string

Pylint 2.11 introduced new checker:
> Used when we detect a string that is being formatted with format() or
  % which could potentially be a f-string. The use of f-strings is
  preferred. Requires Python 3.6 and ``py-version >= 3.6``.

- f-strings are not mandatory
- format can be more readable
- there are ~5.5K spotted issues
