2.1.0 Release Candidate

[trivialfis]

We are about to release version 2.1.0 of XGBoost. We invite everyone to try out the release candidate (RC).

The 2.1.0 release will not include the R interface due to #9810 . We will update the R package once the new interface is complete. Stay tuned.

Roadmap: #10339
Release note: #10378

Feedback period: until the end of June 7, 2024. No new feature will be added to the release; only critical bug fixes will be backported.
