🐛 Enable indentScriptAndStyle by default for HTML and Svelte to align with Prettier

Environment information

CLI:
  Version:                      2.3.7
  Color support:                true

Platform:
  CPU Architecture:             aarch64
  OS:                           macos

What happened?

I suggest changing the default value of indentScriptAndStyle to true for HTML and Svelte.

The current decision (discussed in PR #7333) seems to rely on Prettier's default value of vueIndentScriptAndStyle for Vue. The statistics in PR probably reflects Vue usage patterns rather than for HTML or Svelte.

In fact, Prettier defaults to indenting <script> and <style> tags in HTML and Svelte, treating Vue as an exception.

The issue that introduced the Vue-specific option (see Prettier Issue #3888) shows that most participants voted to indent; however, the default remained false for backward compatibility.

Expected result

HTML and Svelte: set the default of indentScriptAndStyle to true.

Vue: keep the default as false (matching Prettier's vueIndentScriptAndStyle), or follow the indentScriptAndStyle setting if we want consistency across languages.

This is similar to how Biome handles package.json (where expand is enabled by default to match common expectations).

Can you make it a discussion? That's not actually a bug

I'm sorry, but I may not have permission to do this; there is no "Convert to discussion" button.

Canonical svelte has script indented. Easy enough to do

"html": { "formatter": { "indentScriptAndStyle": true } }

though.
