tinymist extension version: v0.10.3

Logs:

There is no related error can be grabbed either from the output of Tinymist server or the VSCode devtool, it is located in the output of VSCode Extension Host.

2024-03-17 03:45:31.520 [error] Error: ENOENT: no such file or directory, open 'c:\Users\Falke\.vscode\extensions\myriad-dreamin.tinymist-0.10.3-win32-x64\out\editor-tools\index.html' tinymist.showTemplateGallery {"value":"myriad-dreamin.tinymist","_lower":"myriad-dreamin.tinymist"}

And the message from popout window is quite straightforward. Looking up the directory of extension also reveals the reason: there is no existence of the required file.

Moreover, there is an error emitted frequently in VSCode devtool, but it seems not interfering critical functions and performance:

The vscode variable may not process some string correctly so I try-catch it. It should not be triggered frequently, so I identity it as an enhancement: I'll implement it by myself when I schedule a time. Anyway it is not related and is an separately issue.
