ts(2307) error keeps showing in the vscode diff editor's left-side (after upgraded to 1.1.x)

[ecoms-ye]

Environment

• Vue: 2.7.14 (from npm create vue@2)
• Volar: 1.1.0 & 1.1.1
• vscode: 1.75.1
• WSL2 (ubuntu 22.04)

Description

Cannot find module 'vue' or its corresponding type declarations.ts(2307)

After upgraded to 1.1.x, import in .vue file would show this ts(2307) error in vscode's "Source Control" diff editor.

Expectation

Do not show ts(2307) error in the diff editor if there is no error.

Just like #2389, I think it's another display bug because the same code right-side works as usual.
