fix(cli): Set COREPACK_ENABLE_AUTO_PIN=0 during local pack of github packages

[islandryu]

Different Corepack versions caused discrepancies in the addition of packageManager during Yarn installation, resulting in checksum changes and installation failures. This commit standardizes the behavior to avoid such errors.

What's the problem this PR addresses?

issue

Error occurs because checksum changes with different corepack versions.

repro

  "dependencies": {
    "react-native-scrollable-tab-view": "https://github.com/ptomasroos/react-native-scrollable-tab-view#74c3ce7332c706732ef0e590c31e6558e8c0f2d5"
  }

When I generate yarn.lock with corepack0.18.0 and install with 0.29.4, I get the following error.

react-native-scrollable-tab-view@https://github.com/ptomasroos/react-native-scrollable-tab-view.git#commit=74c3ce7332c706732ef0e590c31e6558e8c0f2d5: The remote archive doesn't match the expected checksum

This is at least the environment in which it occurred to me.
I also think it probably occurs in any github url

why

The github pakcage is packed locally by running the yarn pack command
It seems that corepack changes the checksum of the package by setting the packageManager field to package.json when this command is executed.

How did you fix it?

Set COREPACK_ENABLE_AUTO_PIN to not add packageManager field
