[amplify_secure_storage_dart] Update win32 dependency to ^6.0.0

[adamtester]

Description

amplify_secure_storage_dart (v0.5.10) depends on win32 ^5.14.0. This prevents any Flutter project using Amplify from upgrading to newer versions of popular packages that now require win32 ^6.0.0, including:

• package_info_plus >= 10.0.0
• share_plus >= 13.0.0

Steps to reproduce

Add both amplify_flutter and package_info_plus ^10.0.0 to pubspec.yaml:

dependencies:                                                       
  amplify_flutter: ^2.10.0
  package_info_plus: ^10.0.0                                                                                                                                                                                                                   

Run flutter pub get:

Because package_info_plus >=10.0.0 depends on win32 ^6.0.0
  and amplify_secure_storage_dart >=0.5.7 depends on win32 ^5.14.0,                                                                                                                                                                            
  package_info_plus >=10.0.0 is incompatible with amplify_flutter >=2.6.5.                                                                                                                                                                     

Expected behavior

amplify_secure_storage_dart should support win32 ^6.0.0 so projects can use the latest versions of other first-party Flutter packages.

Environment

• Flutter 3.41.6 / Dart 3.11.4
• amplify_flutter 2.10.0
• amplify_secure_storage_dart 0.5.10

This is the same pattern as previously filed in #5255 and #6349 for package_info_plus version bumps.
