Description

In T320559 we introduced a new MediaWiki/Http/Telemetry class which took the responsibility of handling Telemetry data - including the X-Request-Id handling.
WebRequest::getRequestId and WebRequest::overrideRequestId() became deprecated in 1.41 and should be removed in future releases.

Definition of done:

WebRequest::getRequestId() is not used
WebRequest::overrideRequestId() is not used
Methods are removed from the WebRequest class
update docs/Injection.md document on how to inject the X-Request-Id header.

The majority uses of reqId in MediaWiki are not strictly Telmetry related (i.e. no headers or other HTTP subcalls). I wouldn't mind keeping WebRequest::getRequestId()` in its current form as widely used stable API and having it internally use Telemetry indeed as today.

Either way, I suggest we at least wait with that until the Telemetry singleton has stabilized a bit. For example, if we can make it a simple class that requires no configuration or MW integration, then we can move callers to that instead of having to a second round of deprecations and replacements. In particular, the human side of feeling a shift in the ecosystem I'd like to reduce given how much of a bad rap MW already has as constantly breaking-change everything (which is interesting, since the same code also as a bad rap for not changing much, which is polar opposite).

It seems that WebRequest::getRequestId() has been deprecated in the latest version of the MediaWiki core repository, based on what I observed in the code.
