doc: write release notes for Go 1.22

[heschi]

This is the tracking issue for writing the Go 1.22 Release Notes. The version at tip can be viewed at https://tip.golang.org/doc/go1.22.

When the Go 1.22 Release Notes are complete, this should be closed, and a similar issue should be made for the next release. The previous issue was #58645.
