fix(auth): replaced authentication middleware with one intended for post requests. (Note: docker node 18 -> 20)

[andrewsu31098]

Problem

BB-813
The cbReviewModal is triggering a post request whose URL is being
stored and used as a redirection link later on during authentication.
This creates a redirection bug when a user attempts to sign in on any of the pages with said cbReviewModal.

• edition groups
• authors
• series

Solution

The route handler for /critiquebrainz/refresh has been updated to use
isAuthenticatedForHandler (which authenticates without redirecting) instead of isAuthenticated which was filling in the redirect link.

Areas of Impact

• Server /critiquebrainz/refresh post endpoint has been updated.
• Docker Node Version updated from 18->20 due to version 18 Node's incompatibility with new Mocha Version.
