Change the retool forum category colors back

Kind of a nitpick -
Recently the colors for the Retool forum categories have changed (feature requests used to be green & App building used to be called support and was blue I think)

Now that there are more categories with very similar colors its hard for me to distinguish between the different categories. To me app building, Tips & Tricks and feature requests all look like the same color.

Hey Joey! Super valid. Do you have any alternative color suggestions/patterns? I don't have too many to pick from (using pretty much every color for our topics :sweat_smile:), but not attached to their order at all and happy to move them around!

(To start, I can definitely make App Building blue and Feature Requests green)
