Rest of doc references 5.16 but this is from 5.19 so added the clarification.

* Update for TS7

I am testing Typescript 7's JS support, which I've largely rewritten
during the switch to Go. That means Javascript code will need to change
much more than Typescript code. Fortunately, most of the changes are for
the better: Javascript semantics are now nearly identical to Typescript
semantics. It's much stricter and no longer has some persistent bugs
that arose from shady JS handling I wrote years ago.

This PR changes Svelte so that it compiles both with TS5.* and TS7,
which means that occasionally there are duplicative or non-obvious
changes. I'll annotate the interesting changes to explain why I made them.

Because TS7 is quite a way off, I don't know whether you'll want to take
this PR. Most of the changes are for the better, because they're due to
stricter TS-aligned checking. But some are neutral and there is the
previously mentioned duplication in a few places.

…yed (#16601)

* fix: skip effects inside dynamic component that is about to be destroyed

When a dynamic component was updated to a different instance and its props were updated at the same time, effects inside the component were still called with the already-changed props.
The fix is to mark the branch as skipped to never got to those effects.

Fixes #16387

* chore: add script to generate test from playground

I often play around with stuff locally and then turn it into a test, this automates the last mile of that
