Consideration: Auto completion for level option

[bogeychan]

Description

The level option doesn't support auto-completion:

pino/pino.d.ts

Line 347 in 9328478

level?: LevelWithSilent | string;

LiteralUnion makes this possible (without type errors for custom string): microsoft/TypeScript#29729

interface LoggerOptions {
    level?: LevelWithSilent | (string & {});
    // ...
}

This would improve the developer experience.

Implementation

However, I don't know if it can be implemented yet, ...

typescript 4.4 is mentioned here (doesn't supports it → there won't be any auto-completion, the behavior should be the same as now):

pino/pino.d.ts

Line 16 in 9328478

// TypeScript Version: 4.4

but version 5.3.1 is used in package.json, this version already supports the technique used in LiteralUnion:

pino/package.json

Line 100 in 9328478

"typescript": "^5.1.3",

Happy to bump TypeScript!
