[New-bugs-announce] [issue46120] Add note to `typing.Union` that it is recommended to use `|` instead

[Nikita Sobolev]

New submission from Nikita Sobolev <mail at sobolevn.me>:

As discussed in https://mail.python.org/archives/list/typing-sig@python.org/thread/TW5M6XDN7DO346RXMADKBAAGNSZPC4ZQ/

> we could probably stick a huge notice in the typing.Union docs saying `|` is preferred for readability in most cases, and not deprecate it for now.

I will send a PR to `Union` and `Optional` docs with this note today.
