Problem & expected behavior (under 200 words)

We recently migrated in node 22.20.0. This resulted in a warning when starting our app using tsx

(node:1) ExperimentalWarning: Use `importAttributes` instead of `importAssertions`

We noticed that the package is already suppressing the warning when using assert instead of with when importing JSON. However, the message changed in node 22.20.0 to the above one, resulting to not being suppressed it anymore.

Is it possible to add the above warning in the suppressing warnings?

Bugs are expected to be fixed by those affected by it
