[bitcoin-wallet-snap] dApp keyring connection

As a dApp developer I would like to have access to keyring to enable users to have interactions with Bitcoin dApps.
I want to connect my origin to the snap,
So that it provides me with accounts and sign methods.

At the moment Metamask's snap doesn't allow any connections from any origin.

Could you please let me know if it's a planned feature or there is another way to interact with bitcoin wallet?

## Technical notes:
https://github.com/MetaMask/snap-bitcoin-wallet/blob/main/packages/snap/snap.manifest.json#L34

Start by reading packages/snap/snap.manifest.json at line 34 and review the issue's description of origin connections. Determine whether the snap can expose accounts and signing methods to dApps, and treat support for an origin connection with those capabilities as the completion criteria.
