Remote .internal override from untrusted URL tests (#26372)

Adding `.internal` to a test file prevents it from being tested in build
mode. The best practice is to instead gate the test based on whether the
feature is enabled.

Ideally we'd use the `@gate` pragma in these tests, but the `itRenders`
test helpers don't support that.
