Add missing handleRejections in logger options

[t-moennich]

In the future this should extend from a subset of TransportStream in https://github.com/winstonjs/winston-transport/blob/master/index.d.ts

Fixes #1801

Can someone please merge this PR urgently? It's quite an important and core feature to be able to log uncaught exceptions.

The proposed changes are incomplete, rejections key on Logger still remain undocumented.
RejectionHandler type needs to be defined and rejections: RejectionHandler; added after line 96

winston/index.d.ts

Lines 90 to 99 in 7d0466f

	interface Logger extends NodeJSStream.Transform {
	silent: boolean;
	format: logform.Format;
	levels: Config.AbstractConfigSetLevels;
	level: string;
	transports: Transport[];
	exceptions: ExceptionHandler;
	profilers: object;
	exitOnError: Function | boolean;
	defaultMeta?: any;

Public API for RejectionHandler is the same as that of ExceptionHandler, so copy-pasting interface ExceptionHandler with a different name should do.

upd: Just noticed that pull request #1842 introduces these exact changes

are handleRejections and rejectionHandlers added in LoggerOptions in the lastet winston version ?

No. Latest version was published on June last year - winston@3.3.3 and winston-transport@4.4.0. In both packages only properties related to unhandled exceptions are documented.

This should be solved via #2021 and go out in the next release. Thanks!
