Tweak wording

[jeffwidman]

"Assure" isn't quite the right word here. Probably meant "ensure"... tweaked the wording a little.

Contributor checklist

• [ ] Provided the tests for the changes.
• [ ] Assure PR title is short, clear, and good to be included in the user-oriented changelog

Maintainer checklist

• [x] Assure one of these labels is present: backwards incompatible, feature, enhancement, deprecation, bug, dependency, docs or skip-changelog as they determine changelog listing.
• [ ] Assign the PR to an existing or new milestone for the target version (following Semantic Versioning).
