improvement(env get) - print npm ignore entries in env get command

[GiladShoham]

This pull request includes changes to the PkgService class in the scopes/pkg/pkg/pkg.service.ts file to enhance the handling and display of package configuration and npm ignore entries. The most important changes include parsing the configuration JSON, extracting specific properties, and updating the rendering method to display these properties in a more structured format.

Enhancements to configuration handling and display:

• scopes/pkg/pkg/pkg.service.ts: Modified the render method to parse the configuration JSON, extract packageJsonProps and npmIgnore, and display them with appropriate titles using chalk.
• scopes/pkg/pkg/pkg.service.ts: Updated the getDescriptor method to include npmIgnore in the configuration object and serialize it to JSON.
