The unit of time expander linter shouldn't always suggest plurals even when the number is not "1"

**Describe the bug**

> **Sub 100-ms response times** with SQLite FTS5 search

In a context like this we would write "Sub 100 millisecond response times" and not "Sub 100 milliseconds response times".

Start by reproducing the unit-of-time expander linter on the quoted “Sub 100-ms response times” example and locate the rule responsible for expanding the unit. Done means the example uses singular “millisecond” after 100 while ordinary cases that require a plural still behave correctly.
