Issue:
Run install scripts in `pnpm@10`
In [`pnpm@10`](https://github.com/pnpm/pnpm/releases/tag/v10.0.0), install scripts must be individually enabled.

> Lifecycle scripts of dependencies are not executed during installation by default!

If not, the following message will be logged.

> The following dependencies have build scripts that were ignored: @sveltejs/kit, esbuild

> To allow the execution of build scripts for these packages, add their names to "pnpm.onlyBuiltDependencies" in your "package.json", then run "pnpm rebuild"

What if this field is added to the `package.json` if the user selects pnpm?

```
◇  Which package manager do you want to install dependencies with?
│  pnpm
```

```json
{
  "pnpm": {
    "onlyBuiltDependencies": [
      "@sveltejs/kit",
      "esbuild"
    ]
  }
}
```

Pull request description:
feat: support `pnpm` version `10`
closes #424 
closes #388 

* updates monorepo to `pnpm@10` to be able to reproduce the error described in the issues above
* adds `esbuild` to `onlyBuiltDependencies` when the users selects `pnpm` during project initialization. This not only applies to project initialization, but to all projects that are using `pnpm` (even existing ones, as soon as you add another add-on to your project)
* exposes the new `sv.pnpmBuildDependendency` api, so that add-ons like `drizzle` (for `better-sqlite3`) can provide further packages that should be added to that list.
