Missing KeycloakConfig Parameter public-client

### Describe the bug

The `KeycloakConfig` typedef is defined here:

https://github.com/keycloak/keycloak-nodejs-connect/blob/cc4bb724fd3fd3fc153283d54f5868303b33418c/keycloak.d.ts#L20

However in Keycloak 18, the config JSON is being generated as such:

Providing the `public-client` parameter to the `KeycloakConfig` object causes an error. Suggest updating the typedef to:
```typescript
interface KeycloakConfig {
'confidential-port': string|number
'auth-server-url': string
'resource': string
'ssl-required': string
'bearer-only'?: boolean
realm: string
'public-client': boolean;
}
```

### Version

18.0.2

### Expected behavior

Expectation is that KeycloakConfig contains all attributes that can be generated by the Keycloak server

### Actual behavior

KeycloakConfig is missing a parameter

### How to Reproduce?

Try to add the `public-client` parameter to a KeycloakConfig results in a compilation error

### Anything else?

_No response_

Open keycloak.d.ts at the linked KeycloakConfig definition and compare it with the Keycloak 18 config described in the issue. Update the typedef so a config containing public-client compiles, then verify that the example configuration is accepted by the type definition.
