`parseUrl` option is missing from the `Configuration` type in v11

In v11 (11.0.3), the Typescript declaration for nano()'s configuration object is missing the `parseUrl` parameter.

`lib/nano.d.ts`:

```ts
/** Nano configuration */
interface Configuration {
/** The URL of the CouchDB service, including username and password if required e.g.
* http://username:password@hostname:port
*/
url: string;
/** For cookie authentication */
cookie?: string;
/** HTTP Agent options
* @see README: {@link https://www.npmjs.com/package/nano#pool-size-and-open-sockets}
*/
agentOptions?: AgentOptions | typeof undici.Agent | typeof undici.MockAgent | typeof undici.Dispatcher;
/** Logging function
* @see README: {@link https://www.npmjs.com/package/nano#logging}
*/
log?(id: string, args: any): void;
/** Set to false to prevent parsing of url
* @see README: {@link https://www.npmjs.com/package/nano#configuration}
*/
headers?: object;
/** Custom request headers
* @see README: {@link https://www.npmjs.com/package/nano#configuration}
*/
}
```

But `parseUrl` is still used in `lib/nano.js`, and documented in the README:
```js
module.exports = exports = function dbScope (cfg) {
let serverScope = {}

if (typeof cfg === 'string') {
cfg = { url: cfg }
}

assert.strictEqual(typeof cfg, 'object',
'You must specify the endpoint url when invoking this module')
assert.ok(/^https?:/.test(cfg.url), 'url is not valid')

cfg = Object.assign({}, cfg)
serverScope.config = cfg
const dummyLogger = () => {}
const log = typeof cfg.log === 'function' ? cfg.log : dummyLogger
const parseUrl = 'parseUrl' in cfg ? cfg.parseUrl : true

...
```

Start by reading the Configuration interface in lib/nano.d.ts and compare it with the parseUrl handling shown in lib/nano.js and the README configuration documentation. Done means the v11 declaration exposes the existing parseUrl option with documentation consistent with its behavior.
