chore(deps): update stencil core

[christian-bromann]

We have shipped various of improvements to the Stencil project and runtime. You can take a close look at our changelog but since v4.20.0 we mainly shipped improvements on the following issues:

Major Improvements:

• Enhanced Shadow DOM and hydration support
  • Improved client-side hydration for SSR
  • Better handling of shadow root styles and component hydration
  • More reliable serialization of Shadow DOM components

Key Bug Fixes:

• Resolved performance issues due to detached nodes in memory
• Fixed several critical issues with scoped slots and component styling
• Improved handling of SVG class attributes and template tags
• Enhanced runtime decorator functionality
• Better handling of form-associated callbacks

Technical Updates:

• Updated to TypeScript 5.5
• Added support for customizable Mermaid diagram colors in documentation

I don't see any critical changes that may impact Ionic users and feel confident we can ship this.

Definitely worth verifying this! I created a dev build 8.4.2-dev.11736797843.16cc5058 which we currently use to test.

@christian-bromann I'm encountering the same errors with Stencil 4.26.0, and they only occur when using React.

[a7medm7med]

@christian-bromann The same type of error also occurs in Vue (I haven't tested it in Angular yet).

Fyi, I've tested this locally and upgrading to 4.27.2 it does not appear to fix #30215 (in Angular)

@christian-bromann do you by any chance know if this is a bug in Ionic or should be replicated in Stencil to be fixed there? Thanks

I tested the dev build out in an Ionic JavaScript project using Vite, the Ionic Angular conference app, Ionic React conference app, and Ionic Vue conference app. I could not find any issues in my testing. Great work on this! 🎉
