Add `AnyLogger` type (`Logger | LoggerAdapter` alias)

Feature or enhancement

Proposal:

AnyLogger: TypeAlias = Logger | LoggerAdapter

According to the docs, LoggerAdapter should look mostly like Logger. So it would be really nice to have a type that can be used for both Logger and LoggerAdapter.

I would need it when I want to hold a logger instance, but I don't really care if it's Logger or LoggerAdapter.
So I want to support both options.

It may sound like an antipattern, according to the docs, but using LoggerAdapter is the recommended way of passing contextual info (according to the docs).

Even when using contextvars for holding the logger, a AnyLogger type would be handy indeed.

I am willing to submit a PR fixing this issue, like I tried to do before:

Has this already been discussed elsewhere?

從 logging 模組的 Logger 和 LoggerAdapter 入口開始，檢視 issue 中所示的提議 TypeAlias。查看先前的 pull request 以了解實作背景，然後確認產生的型別涵蓋兩種 logger 形式，同時不改變其文件所述的行為。
