This change makes it so that we show the name of the project that is
selected on the selection button instead of the ID. There is a chance
that the name is not unique, but I'm willing to take that risk (plus
it's how we do it today).
I've used a useMemo for this, because we have to scan through a list
to find the right project. Sure, it's always a small list (less than
500 items, I should think), but still nice to avoid doing it every
render. Happy to remove it if you think it obfuscates something.
We *could* also use a `useState` hook and initialize it with the right
value, update when it changes, but I actually think this is a better
option (requires less code and less "remember to update this when that
changes").
This change wraps the project selection option in the
CreateFeatureDialog in a conditional that hides it when Unleash is
OSS.
OSS doesn't have access to the project creation API, so there's no
point in showing this.
