Old-styled svelte-ignores are ignored with Svelte 5

[shadow-identity]

Before You File a Bug Report Please Confirm You Have Done The Following...

• [X] I have tried restarting my IDE and the issue persists.
• [X] I have updated to the latest version of the packages.

What version of ESLint are you using?

9.3.0

What version of eslint-plugin-svelte are you using?

2.39.0

What did you do?

Configuration

I use default configuration provided by `npm create svelte@latest` ``` import js from '@eslint/js'; import svelte from 'eslint-plugin-svelte'; import globals from 'globals'; /** @type {import('eslint').Linter.FlatConfig[]} */ export default [ js.configs.recommended, ...svelte.configs['flat/recommended'], { languageOptions: { globals: { ...globals.browser, ...globals.node } } }, { ignores: ['build/', '.svelte-kit/', 'dist/'] } ]; ```

<!-- svelte-ignore a11y-click-events-have-key-events a11y-no-static-element-interactions -->
<my-tag on:click={() => {}}>
</my-tag>

<div />

What did you expect to happen?

Like when Svelte 4.2.17 is used, a11y-click-events-have-key-events and a11y-no-static-element-interactions should not be reported.

Also element_invalid_self_closing_tag was also not reported with Svelte 4, so IMO should not be reported in legacy mode with Svelte 5.

What actually happened?

Additional comments

I think the reason of the mess is that svelte 5 uses underscores in warning names. But according to Svelte developers, old-styled components (which does not use runes) should keep working: https://github.com/sveltejs/svelte/issues/11666

After https://github.com/sveltejs/svelte/issues/11666 was fixed, svelte-check does not report this markup.

I also put <div /> case, it was also not reported with Svelte 4 (it is reported with svelte-kit tho).
