[FEATURE] GIF Picker (giphy, tenor, etc)

The Pitch
Alright, I'll say this behalf on everyone. Everyone loves adding GIFs. GIFs bring out the real mood, a form of expressionism as some might call it. You know what they say? A picture is worth a thousand words.

Why It's Needed
GIFs are essential for communication, but I can understand not everybody needs them. Let's say you just released a big gigantic feature for your product, and want an image to fit the mood? Open the embedded GIF picker and add one, simple as that.

Requirements
Not everyone needs GIFs. A GIF picker should be disable able, whitelistable, blacklistable, and only display non NSFW content. Productlift has markdown support, right? This means a little image tag, with a URL from respective GIF api, and your good to go! Most product board solutions don't even have this feature. Canny? nope! Productboard? nope! Aha!? nope! This would be a great feature to extend customer communication. Teams too! Who knows, maybe even Robert from IT wants to send a GIF!
