_content/doc/go1.24: don't refer to parameter names in release notes

The release notes do not contain the full function signature,
therefore parameter names don't have context. Describe in words
instead.

Also, for the bytes package, use "subslice" instead of
"substring".

Also added some words for clarification, and did minor format
changes.

For golang/go#68545.
