### Steps to reproduce
See https://github.com/edaniszewski/pylint-quotes/issues/24
See `pylintrc` in attached [pylint_bug.zip](https://github.com/PyCQA/pylint/files/6393225/pylint_bug.zip)
```bash
python -m venv venv
. venv/bin/activate
pip install -r requirements.txt
pylint --rcfile pylintrc demo.py
```
### Current behavior
Running this configuration on a file containing:
```
foo = "bar"
```
results in an exception:
```
Traceback (most recent call last):

if (2, 2, 2) < pylint_version:
TypeError: '<' not supported between instances of 'int' and 'str'
```
### Expected behavior
`pylint` should not throw exceptions, and instead generate report complaining about the use of double quotes (`""`) and illegal variable name `foo`.
### pylint --version output
Result of `pylint --version` output:
```
→ pylint --version
pylint 2.8.2
astroid 2.5.6
Python 3.8.3 (default, Feb 26 2020, 00:00:00)
[GCC 9.3.1 20200408 (Red Hat 9.3.1-2)]
```
Additional dependencies:
```
pylint-quotes==0.2.1
```
### Probable cause:
1. `pylint` seems to have just changed versioning scheme: https://github.com/PyCQA/pylint/compare/pylint-2.8.1...v2.8.2
2. Which broke this line: https://github.com/edaniszewski/pylint-quotes/blob/master/pylint_quotes/checker.py#L360Match evidence

TypeErrorpylint_versionpylint/__pkginfo__.pypylint-dev/pylintPylint 2.8.2 broke pylint-quotes__pkginfo__numversionrun_pylintPylintRunlinter.check_check_files_check_astroid_moduleTechnical objective
Restore a usable, order-comparable numeric version representation for the pylint distribution so that third-party checkers which compare pylint's version against a plain tuple of integers keep working.
Success condition
running pylint with a plugin that performs a comparison such as (2, 2, 2) < pylint_version completes and produces the normal lint report rather than aborting with a TypeError; the version information pylint exposes remains correct for the current release, including for pre-release/dev version strings.
