feat(@vben/plugins): tiptap 组件新增 maxHeight 属性支持及文档 (#7897)

* feat(@vben/plugins): tiptap 组件新增 maxHeight 属性支持

- 新增 maxHeight prop 支持限制编辑器最大高度
- 编辑器内容区超出最大高度时自动滚动
- 移除 style.css 中未使用的 CSS 规则

* docs(@vben/plugins): 添加 tiptap 富文本编辑器组件文档

- 新增中文文档 docs/src/components/common-ui/vben-tiptap.md
- 新增英文文档 docs/src/en/components/common-ui/vben-tiptap.md

* fix(@vben/plugins): extract URL from response in image upload callback

The upload callback was incorrectly passing the AxiosResponse object
to resolve() instead of extracting the actual image URL string.
This caused the editor to insert [object Object] as image src,
resulting in broken images.

* chore: add changeset for tiptap maxHeight feature

* Revert "chore: add changeset for tiptap maxHeight feature"

This reverts commit a28fc4441f14641f6af6c1a143aa6959591315b2.
