feat: multi language support signal

[huang-benny]

This PR adds a new multiLanguageSupport signal to the QUALITY pillar that measures how many programming languages are supported by a CDK construct through jsii compilation. This provides insight into the package's accessibility and usability across different repositories.

Changes:

• Fetches jsii configuration from package.json via NPM registry API
• Extracts the jsii.targets object to identify supported language bindings
• Returns 0 if jsii is not configured or targets are empty
• Added analyzeJsiiLanguageSupport() function to count supported languages
• Counts language targets (python, java, dotnet, go, etc.) from jsii configuration
• Added unit tests for jsii language detection

Scoring (typescript is included in all libraries by default):

• 4 additional languages: 5 stars
• 3 additional languages: 4 stars
• 2 additional languages: 3 stars
• 1 additional language: 2 stars
• 0 additional languages: 1 star

Example CLI Input and Output:

> cdk-construct-analyzer cdk-ecr-deployment --details  

LIBRARY: cdk-ecr-deployment
VERSION: 4.0.3
