chore: fix weird formatting in recent changelog entry (#10257)

* Fix weird formatting in recent changelog entry

A recent auto-generated changelog entry had a `<p>` in it, which caused the Markdown rendering to look strange. Replacing `<p>` with `&lt;p&gt;` fixes the rendering.

* Update packages/svelte/CHANGELOG.md
