Links to docs and opening a GH ticket in deployed web apps

[David Choi]

Create a docs page in our deployed console and a link to open an issue:

• Create /docs page that links to w3cli (https://github.com/web3-storage/w3cli#getting-started) and w3up-client (https://github.com/web3-storage/w3up-client#about) READMEs as suggested docs for users, as well as links to the w3protocol, w3spec, and w3infra repos further below
• Next to the Terms link at the bottom-left of the console when signed in, have links to Docs (which goes to /docs) and Support which goes to https://github.com/web3-storage/w3ui/issues
