fix(cli/program_state): Remove redundant compiler warning

[nayeemrmn]

As I see it, #6760 introduced a valid fix for a strictly internal quirk where type-only modules used to cause problems. But the accompanying warning isn't necessary because it affects valid user code.

I totally disagree with the intent of this PR. The message is not redundant. People should not be importing type only d.ts files via import and should instead use import type, as the resulting code is not --no-check safe, and can/will result in other errors. If people are trying to import ambient types, they should be using import at all but instead using triple slash directives.

😓 I could have sworn I saw this warning without using any d.ts files, but I can't reproduce anything now. Closing.

@nayeemrmn there were some bugs related to #8311 that was causing this to occur incorrectly, so you or other could have incorrectly seen this (caused when another file had a diagnostic error, which was then fixed, but a dependency was not changed)
