fix: add getScriptKind to host for Vue JSX/TSX support

[susanforme]

Fix: not working for Vue files with <script lang="jsx"> or <script lang="tsx">

Problem

When using prettier-plugin-organize-imports with Vue files that have <script lang="jsx"> or <script lang="tsx">, unused imports are not removed and import sorting may silently fail.

Root Cause

During decoration, Volar's decorateLanguageServiceHost checks whether the host provides a getScriptKind method. If this method is missing, Volar skips overriding getScriptKind, which means TypeScript has no way to know that a virtual file generated from <script lang="jsx"> should be parsed as JSX.

TypeScript then defaults to treating the content as plain TS, fails to parse JSX syntax like <div>, and organizeImports returns an empty array — so no imports get removed.
