doc-en Add deprecation/changelog for switch statement semicolons.

I'm not sure if it makes sense to use the "deprecated" entities here, since it's just a tiny part of the syntax that's deprecated, not the whole thing. The "feature" warning seems like it would be overkill. So I just adjusted the text and added a changelog.

I find it appropriate. This what it's for. See also: https://www.php.net/manual/en/info.configuration.php#ini.assert.active where the snippet is used for various INIs.

I'm not sure what to do with the changelog here. It seems like we're going to need to redo the whole file to allow it to use a section tag? That seems... scope creepy, but also a blocker. Please advise, someone who knows this better than I do.

I'm not sure we need the changelog. I don't think this was previously done for similar pages / it was only done for functions.
