`vscode-web` module doesn't apply settings.json and takes long time to install

For context, I'm using `vscode-web` module on Coder template, I defined module in main.tf as follow:

```tf
module "vscode-web" {
source = "registry.coder.com/modules/vscode-web/coder"
version = "1.0.22"
agent_id = coder_agent.main.id
extensions = [
"github.copilot",
"ms-python.python",
"ms-toolsai.jupyter",
]
accept_license = true

# my personal settings.
settings = {
"workbench.colorTheme" = "Dark Modern",
"terminal.integrated.cursorBlinking" = true,
"terminal.integrated.cursorStyle" = "line",
"terminal.integrated.cursorStyleInactive" = "none",
"terminal.integrated.fontSize" = 16,
"git.autofetch" = true,
"editor.fontSize" = 16,
"editor.suggestSelection" = "first",
"editor.linkedEditing" = true,
}

folder = "/workspaces"
}
```

First, it takes long time to install vscode on workspaces create from template, this build timeline that I capture from coder web:

Since other modules don't take much time like vscode-web, I think it is `vscode-web`'s problem.

And second, even I spec my personal settings.json but it's not apply on vscode-web (extensions still works well)

Help me, please. Thank you.
