Add intentionally misspelled word to spell check ignore list

One of the unit tests for the JSON schema validation interpretation code contains an intentionally misspelled word. This
word has been added to the codespell misspelled word dictionary in the latest release, causing the spell check and its
workflow runs to start failing.

The spell check failure is hereby resolved by the addition of the intentionally misspelled word to the ignore list in
the codespell configuration file.
