Standardize on Peer ID or PeerID (or...PeerId)

[stephendonner]

Description

(Yes, sorry, this is a tad pedantic.)

We've got IPFS peer IDs written as Peer ID and PeerID - let's choose one, for consistency's sake.

Steps to Reproduce

1. new profile
2. launch Brave
3. load brave://ipfs
4. look at the copy for instances of Peer ID and PeerID

Actual result:

Expected result:

Should be consistently either Peer ID or PeerID (although https://github.com/libp2p/js-peer-id/tree/e19da79f08f8dc6924a72a688ce563c7fd7b1989#description has it as PeerId in places, heh).

@lidel - which is it, pretty please? 🙇
