fix(vscode): Remove azure identity and restrict hybrid for public cloud

[ccastrotrejo]

This pull request includes several changes to the vs-code-designer application, primarily focusing on updating dependencies and refactoring the LogicAppResolver class to use existing credentials from the subscription context.

Dependency updates:

• Removed the @azure/identity dependency.

• Updated the LogicAppResolver class to use subContext.credentials instead of creating a new DefaultAzureCredential instance.

• Added a conditional check to only push promiseHybridLogicApp to the resolver promises if the resourceManagerEndpointUrl is 'https://management.azure.com/'.

Fixes #6149
