Add sys.version_info guard to import-error

[cdce8p]

Description

Suggested by @KapJI here: home-assistant/core#50444 (comment)

Don't emit an import-error if import is guarded behind if sys.version_info. Since pylint can only check the python version it's executed with, this often results in a false-positive.

The current suggestion doesn't account for imports that are truly missing, since the if statement can't (yet) be easily inferred. Implementing this would be possible, but probably not worth it.

Examples

import sys

if sys.version_info >= (3, 9):
    import zoneinfo

if sys.version_info[:2] >= (3, 9):
    import zoneinfo

If tested with pylint <= 3.8, this would have resulted in an import-error without this change.
