spec: range over integer expressions underspecified [1.22 backport]

[gopherbot]

@griesemer requested issue #65137 to be considered for backport to the next 1.22 minor release.

@gopherbot please consider this for backport to 1.22. It's missing documentation for 1.22.

Change https://go.dev/cl/559875 mentions this issue: [release-branch.go1.22] spec: clarify iteration variable type for range over integer

The process for landing changes meant for Go 1.22 at this point in the release cycle doesn't require a backport issue. This is documented at https://go.dev/s/release#july--january-week-3-work-on-the-next-release-begins:

While the current release is being stabilized, the tree reopens for work on the next. During this period, fixes intended for the current release need to be cherry-picked onto the release branch. Unlike cherry-picks for minor releases, these changes don’t need a backport issue and don’t need to be approved by the release team. As long as they’re permitted by the freeze policy, they can be reviewed and submitted like any other CL.

Since issue #65137 is already in Go1.22 milestone, please feel free to update the CL description to just mention it and submit it. Thanks.
