Guidance on generating a collector HPKE key

[inahga]

The new task page doesn't provide guidance on how I can acquire/generate a collector HPKE key.

If adopting #378, we can consider having the key generated client side, with the private key being downloadable by the user, and the public key uploaded to DU.

I'd be happy to PR a better description, but we might also have to also consider how it's done? I had to use hpke_keygen, copy the HPKE config field, echo "$(wl-paste)=" | base64 -d >hpke.key--note the padding character that I had to add... I wouldn't expect an end-user to have to do all that.

The issues divviup/janus#1182 and divviup/janus#1602 would improve this situation by making the procedure much shorter. (and cross-platform)

As of #388, the guidance is cargo install divviup-cli --git https://github.com/divviup/divviup-api; divviup -t <API_TOKEN> hpke-config generate

is this safe to close? or does it represent the need to document this in the interface?

Interface documentation was the main goal of this issue, with a simpler means to accomplish it being a (very important) secondary goal.
