document use of asb export-bitcoin-wallet

Add to the `asb` document @delta1's text on exporting the Bitcoin wallet
descriptor and importing the descriptor into Sparrow Wallet.

TODO: maybe it would make sense to add the images to Git, instead of
linking to files on Github?

### Exporting the Bitcoin wallet descriptor
First use `swap` or `asb` with the `export-bitcoin-wallet` subcommand.
Output example:
```json
{"descriptor":"wpkh(tprv8Zgredacted.../84'/1'/0'/0/*)","blockheight":2415616,"label":"asb-testnet"}
```
The wallet can theoretically be directly imported into
[bdk-cli](https://bitcoindevkit.org/bdk-cli/installation/) but it is easier to
use Sparrow Wallet.
Sparrow wallet import works as follows:
* File -> New wallet -> Give it a name
* Select "New or Imported Software Wallet"
* Click "Enter Private Key" for "Master Private Key (BIP32)"
* Enter the `xprv...` or `tprv...` part of the descriptor (example above is `tprv8Zgredacted...`:

* Click "Import"
* Leave the derivation path as `m/84'/0'/0'` and click "Import Keystore" button
* Click "Apply" and then supply password
