Flag mixing up "upcoming" and "up and coming"

## Description

Some people use "upcoming" (due in the near future) when they mean "up and coming" (gaining prominence).
I'm not sure if the opposite is also happening.

## Potential False Positives

I expect it will be hard to tell which uses are right or wrong using heuristics.

The issue names no files, tests, or entry points. Start by reviewing the listed examples and the grammar-checking behavior for “upcoming” and “up and coming”; define how unambiguous cases should be distinguished and what should happen for potential false positives.
