Add discussion that concurrent access to the environment is unsafe

The bug report #27970 has existed for 8 years, the actual bug dates back to Rust pre-1.0. I documented it since it's in the interest of the user to be aware of it. The note can be removed once #27970 is fixed.

Preserve potential mood for equal or NUL sign

2023-04-03T17:30:20+00:00

Original `var_os` description said that it _may_ return an error if the value contains `=` or NUL. Let's make no promises on the `None` return value in these situation either, keep it in the [potential mood](https://en.wikipedia.org/wiki/Grammatical_mood#Potential).
