[feat] Output artifacts overview to json

[bacelarfc]

This pull request introduces a new feature for exporting artifacts to JSON files and includes several changes across multiple files to support this functionality. The most important changes include modifications to the configuration structure, updates to the program logic, and the addition of a new package for handling the export process.

Configuration Updates:

• internal/bootstrap/viper.go: Added a new Export section to the configuration structure, including an Artifacts subsection with Enabled and Folder fields. Set default values for these new fields. [1] [2] [3]

Program Logic Updates:

• internal/program.go: Updated the program function to include a step for exporting artifacts to JSON if the feature is enabled. Added the necessary import for the new exportArtifacts package. [1] [2]

New Export Artifacts Package:

• pkg/exportArtifacts/main.go: Created a new package exportArtifacts with a struct ExportOption and a method Run to handle the export of image and chart data to a JSON file.
• pkg/exportArtifacts/main_test.go: Added tests for the exportArtifacts package to ensure the export functionality works correctly and creates the expected JSON file.

Hey 👋
Looks good so far. We are missing the new feature described in the docs:

1. Add entry to configuration table and example
2. Would be cool with an intro example without import but only export
