Trivial Change: Fix Typo in Error Message

Problem Description

A user reported that when they enter an invalid email during registration, the error message says "Invlaid email format" instead of "Invalid email format." The team wants this fixed.

Fix the typo and produce a file named changes.md describing what you changed and why you did or did not create/update a spec.
