[feature] Better pnpm workspace support

[yjl9903]

Is your feature request related to a problem? Please describe.

In my full-stack pnpm monorepo project, I use the following structure to manage my project.

root
├── packages/
│  ├─ shared1/
│  ├─ shared2/
│  └─ ... # packages shared in this repo
└── apps/
   ├─ frontend/ # A frontend project, may use the shared lib
   └─ backend/  # A backend project, may use the shared lib

Now, zeabur can not properly handle the pnpm monorepo correctly.

For installation, the generated dockerfile only copy and install the deps in the root package.json.

For building, I use some monorepo manager to build all the shared library and frontend app (or backend app).

Describe the solution you'd like

Detect the pnpm workspaces, see details in the pnpm docs.

And then generate dockerfile like:

# ...
Copy package.json pnpm-lock.yaml .
Copy packages/shared1/packages.json ./packages/shared1/
Copy packages/shared2/packages.json ./packages/shared2/
RUN pnpm install
# ...

In my previous experience, docker does not support something like glob pattern?
