fix: error editing post when img component has file attribute (#5434)

#### What type of PR is this?

/kind bug
/area editor
/area ui
/milestone 2.14.x

#### What this PR does / why we need it:

使用默认编辑器时，当图片、视频中具有 `file` 属性时，进入编辑界面时会报错。此 PR 将不再从渲染后的 HTML 中获取 file 属性，并且在渲染 HTML 时，抛弃掉 file 属性用于解决这个问题。

#### How to test it?

测试图片上传、视频上传功能不受影响即可。

#### Which issue(s) this PR fixes:

Fixes #5430
