Add components for choosing NWC application to authorize a connection

[rolznz]

NWC is a public spec and there can be many providers. There is a list of providers in alby-js-sdk.

• Add an icon and title to the NostrWebLNOptions type
• Export the list of providers so consumers can render a list manually
• Create components for different rendering libraries without forcing the consumer to install those libraries, starting with React. If the consumer wants to use the components, they need to install e.g. react themselves and then they can import the components. Create Web components, starting with button (which opens a modal)
• Example components: connect button, provider list, modal

Update: we think making Web components using https://lit.dev/ would be better. Then it works with any framework and plain html. CC @bumi
