TransformableInfo Typing out of date.

[dscalzi]

The TransformableInfo key is no longer restricted to only a string. triple-beam changed their typings such that the constants are no longer strings.

see triple-beam change: DefinitelyTyped/DefinitelyTyped#46490

usage in winston: https://github.com/winstonjs/winston/blob/68ea786e053e50b51396e0cc8993c67ff789609c/lib/winston/logger.js#L251

Location of required change: https://github.com/winstonjs/logform/blob/master/index.d.ts#L10

TL;DR the type needs to support strings and unique symbol.

Current ugly workaround for projects using these typings:

import { SPLAT as SPLAT_Symbol } from 'triple-beam'
const SPLAT = SPLAT_Symbol as unknown as string // this is not a string

...
format.printf(info => {
    if(info[SPLAT]) { ... }
})

Yep, running into the same, although I fixed this without casting by just adding the splat to the interface:

import { SPLAT } from 'triple-beam';

declare module 'logform' {
  export interface TransformableInfo {
    // eslint-disable-next-line @typescript-eslint/no-explicit-any
    [SPLAT]: any;
  }
}

Any plans to merge this PR? Running into this issue as well.

@yurijmikhalevich can this be given some attention? Still a problem over a year later and it's causing a big headache getting tsc to work on gh-actions.
