Analytics for create a new collection

[codemonkey800]

Closes #513

[neuromusic]

looks good, however, the plausible "goals" are getting a bit unwieldy. we should consider a naming convention for better tracking. proposed a revision to this goal here (but requires change in plausible, too)

What does "unknown" signify here?

[codemonkey800]

this represents the type of the data payload for the event. for example, here's what it is for filters:

napari-hub/frontend/src/hooks/usePlausible.ts

Lines 21 to 25 in 3e714bd

	Filter: {
	field: string;
	value: string;
	checked: boolean;
	};

since the only thing we need from this event is whether it was fired or not, we don't really need a payload type, so I passed in unknown for now. check this out for more info on the unknown type: https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-0.html#new-unknown-top-type

Ah makes sense! Thanks for the overview!
