Update docs about strict

[Janpot]

If I understand correctly strict means it won't allow a trailing slash to match

Thanks for the catch. There documentation is also shared in TypeScript here (sorry!):

path-to-regexp/src/index.ts

Line 503 in 98ab888

* When `true` the regexp allows an optional trailing delimiter to match. (default: `false`)

.
