Doesn't seem to support pnpm currently.

The loadGlobalPnpmPackage method throws an exception
#81

Current environment

1. The pnpm version is 8.8.0.
2. taze version is 0.11.3.
3. The output of command pnpm ls --global --depth=0 --json is

[
    {
        "path": "C:\\Users\\simexce\\AppData\\Local\\pnpm\\global\\5",
        "private": false
    }
]

Reason
pnpmOut => Object.entries(pnpmOut.dependencies)，pnpmOut.dependencies is undefined.

Also, does not work on Node 22 when taze is installed with bun. taze is installed with npm works.
