chore: make "config" field available to derived classes

[roman-sainchuk]

What/Why/How?

It would be nice to have access to config field in subclasses extending BaseResolver class.
Example:

export class ExternalResolver extends BaseResolver {
  override async loadExternalRef(absoluteRef: string): Promise<Source> {
    if (isHttpPath(absoluteRef)) {
      const { body, mimeType } = await readFileFromUrl(
        absoluteRef,
        this.config.http // Here is the need in config field
      );
      return new Source(absoluteRef, body, mimeType);
    }

    return new Source(
      absoluteRef,
      (await getDocumentByURI(absoluteRef)).getText()
    );
  }
}
