refactor(wsl): relax WSL error judgment

[BlackHole1]

We found that Microsoft sometimes modifies the WSL error codes. To avoid this, we relax the handling of error codes.

Pull Request Overview

This PR relaxes the WSL error judgment to accommodate variations in error codes introduced by Microsoft.

• Removed module-specific prefixes from error message substring checks in MountVHDX, UmountVHDX, and MoveDistro functions.
• Adjusted error handling to be more flexible by checking for core error codes without their former qualifiers.

• Relaxing the error check by removing the module prefix improves flexibility; however, verify that the substring matching will not inadvertently capture unrelated error messages in the future.

if strings.Contains(err.Error(), "WSL_E_USER_VHD_ALREADY_ATTACHED") {

pkg/wsl/distro.go:137

• The removal of the module-specific prefix in the MoveDistro error check makes the matching more permissive; ensure this change does not unintentionally catch non-targeted errors.
