doc: write release notes for Go 1.26

[dmitshur]

This is the tracking issue for writing the Go 1.26 Release Notes. The version at tip can be viewed at https://tip.golang.org/doc/go1.26.

When the Go 1.26 Release Notes are complete, including resolving all known items and those caught by relnote todo, the release-blocker label can be removed. The draft notice stays until it's removed on the day of the release. At that time this issue is closed, and a similar issue is made for the next release. (The previous issue was #71661.)
