Product Page: Make replacement guides difficulty backgrounds gray

[sterlinghirsh]

The guide difficulty is too colorful and eye-catching for how relatively unimportant it is. Make it a gray background like the time estimate. Hide missing time estimates (including "No estimate) and empty/null difficulty.

Why do you think that information is unimportant?

That badge is used all over the website with those color gradation, it should help the user understand the degree of difficulty quickly

Not that it's unimportant, just that it's probably the least important piece of info on that guide card. We'll probably switch the other cases to be grayscale in the future.
