Suggested .vscode/launch.json requires installing vite

[JoshuaKGoldberg]

Clear and concise description of the problem

Going through the VS Code debugging guide in https://vitest.dev/guide/debugging.html#vscode, when I run F5 on a repo that doesn't have vite listed as a dependency:

joshgoldberg ~/repos/template-typescript-node-package $  cd /Users/josh/repos/template-typescript-node-package ; /usr/bin/env 'NODE_OPTIONS=--require "/Applications/Visual Studio Code.app/Contents/Resources/app/extensions/ms-vscode.js-debug/src/bootloader
.bundle.js"     --inspect-publish-uid=http' 'VSCODE_INSPECTOR_OPTIONS={"inspectorIpc":"/var/folders/sr/j__6_9gn0dv557z0xf3p7y8h0000gn/T/node-cdp.67533-14.sock","deferredMode":false,"waitForDebugger":"","execPath":"/Users/josh/.nvm/versions/node/v18.7.0/bi

 MISSING DEP  Can not find dependency 'vite'

? Do you want to install vite? › (y/N)

After accepting with y (or running pnpm install vite manually), the debug command works.

Reproduction:

• Check out https://github.com/JoshuaKGoldberg/template-typescript-node-package/tree/c122ea1aa2e70ed5ead091b345f2b0a424dcd2bb
• pnpm install
• Open src/greet.test.ts
• Launch the Debug Current Test File command

Suggested solution

I don't know why this is happening enough to suggest a solution 😞 sorry. ./vitest.mjs is the bin entry in node_modules/vitest/package.json.

Alternative

No response

Additional context

Note that pnpm test in that repository works without adding vitest as a dependency.

We use isPackageExists from local-pkg library. I guess it doesn't recognize that vite is installed with Vitest 🤔
