Title

Add PackageManagerLoginCommand for Configuring Package Managers in JFrog CLI

Description

This PR introduces the PackageManagerLoginCommand, a unified command for configuring package managers to use JFrog Artifactory. It enables registry setup and authentication across various project types, automatically handling tool-specific settings based on the selected project.

Supported Package Managers

• npm: Configures registry and authentication in the .npmrc file.
• Yarn: Sets up registry and authentication in the .yarnrc or .yarnrc.yml file.
• Pip: Configures PyPI repository URL in the pip.conf file.
• Pipenv: Sets the global index URL in the pip.conf file.
• Poetry: Manages repository and authentication in the pyproject.toml file.
• Go: Configures the GOPROXY (persistent) environment variable to use Artifactory.
• NuGet: Adds repositories and authentication in the NuGet.config file.
• dotnet: Configures repositories and authentication in the NuGet.config file.

Supported Auth Types

• Token-based, Basic (username/password), and Anonymous.

Testing

• Unit tests validate configuration updates for each package manager.

Perhaps we could move the npm and yarn config set/get functionality out of utils and place it under a more focused javascript package (similar to how the python package handles pip, poetry, etc). This could also be a good opportunity to merge any overlapping code between the two for better reusability and maintainability. What do you think?
