This commit is the result of running `yarn eslint --fix` after enabling
the `no-implicit-coercion` ESLint rule.  This rule has been added to
our ESLint config here:

https://gitlab.com/gitlab-org/gitlab-eslint-config/merge_requests/14

**Why?**
This file only contains a few text based helper functions.
It has nothing to do with Vue or Vue components.

Sets `updated_at` so that the transformed note is returned together with
the new reply

Partially addresses #47006.

Closes #44604
