Improve HMR handling for styles, persisted islands (#3492)

Browse source 
* feat: improve HMR handling for styles, persisted islands

* Also using data-persist to keep injected <style>'s during HMR

* Updating E2E tests to validate that .astro HMR doesn't blow away component styles

* chore: add changeset

* copy/paste error when cleaning up tests

* big change - using inline <style> blocks instead of <link>s in dev

* Updating tests that were expecting <link> stylesheets in dev

* updating all E2E tests to use workspace versions for astro deps

* TEMP: adding debug logging to see why the Ubuntu test only fails in CI

* fix: Svelte styles are automatically handled by Vite, we can skip them in dev

* fix: svelte is more interesting, we need Astro to inject styles only until hydration

* avoiding extra HMTL noise by only including the data-astro-injected URL for svelte components

* TEMP: ubuntu CI doesn't like the svelte HMR test...

* disabling the svelte component test on ubuntu for now
