Bump pylint from 2.6.0 to 2.15.6

[dependabot[bot]]

Bumps pylint from 2.6.0 to 2.15.6.

Release notes

Sourced from pylint's releases.

pylint-2.8.1

• Add numversion back (temporarily) in __pkginfo__ because it broke Pylama and revert the unnecessary pylint.version breaking change.

  Closes #4399

pylint-2.8.0

• New refactoring message consider-using-with. This message is emitted if resource-allocating functions or methods of the standard library (like open() or threading.Lock.acquire()) that can be used as a context manager are called without a with block.

  Closes #3413

• Resolve false positives on unused variables in decorator functions

  Closes #4252

• Add new extension ConfusingConsecutiveElifChecker. This optional checker emits a refactoring message (R5601 confusing-consecutive-elif) if if/elif statements with different indentation levels follow directly one after the other.

• New option --output=<file> to output result to a file rather than printing to stdout.

  Closes #1070

• Use a prescriptive message for unidiomatic-typecheck

  Closes #3891

• Apply const-naming-style to module constants annotated with typing.Final

• The packaging is now done via setuptools exclusively. doc, tests, man, elisp and Changelog are not packaged anymore - reducing the size of the package by 75%.

• Debian packaging is now (officially) done in https://salsa.debian.org/python-team/packages/pylint.

• The 'doc' extra-require has been removed.

• __pkginfo__ now only contain __version__ (also accessible with pylint.__version__), other meta-information are still accessible with import importlib;metadata.metadata('pylint').

• COPYING has been renamed to LICENSE for standardization.

• Fix false-positive used-before-assignment in function returns.

  Closes #4301

• Updated astroid to 2.5.3
