flake8-pyi PYI006 bad version info comparison (#3291)

Browse source 
Implement PYI006 "bad version info comparison"

## What it does

Ensures that you only `<` and `>=` for version info comparisons with
`sys.version_info` in `.pyi` files. All other comparisons such as
`<`, `<=` and `==` are banned.

## Why is this bad?

```python
>>> import sys
>>> print(sys.version_info)
sys.version_info(major=3, minor=8, micro=10, releaselevel='final', serial=0)
>>> print(sys.version_info > (3, 8))
True
>>> print(sys.version_info == (3, 8))
False
>>> print(sys.version_info <= (3, 8))
False
>>> print(sys.version_info in (3, 8))
False
```
