…, deps (#6244) #### Details This PR continues the work from #6226 and #6223, adding another layer of injected files to the strict null check list. The only case with a notable behavioral change is that axe-core technically documents in its typings that it's allowed to omit a "how to fix" section from results, but if it were to actually do so, our cards UI would currently crash. I don't think axe-core actually omits that info in practice (I suspect it's there to accomodate custom rules), but now if it were to do so, we'd omit the section from the card rather than crashing (similar to how we handle results with missing snippets). This ended up enabling a *lot* of files to be autoadded! It brings us from ~72% null-strict to ~78% ```markdown ## Web strict-null progress **78%** complete (**1210**/1561 non-test files) *Contribute at [#2869](#2869).
