[FEATURE] Include build artifact in generated projects

[eliashaeussler]

Is your feature request related to a problem?

Once a project is successfully generated, one cannot reproduce the original build state. This makes it hard to understand

• which template basis was used for the generated source files,
• which version of the CPS Project Builder was used to generate the project and
• what user-submitted template properties were used to process source files.

Describe the solution you'd like

A project build artifact should be generated on successful project generation. For example, this can be a JSON file .project-builder/build-result.json with the following content:

{
    "result": {
        "date": "2022-06-27T21:13:07+0200",
        "project-builder": {
            "version": "0.1.7"
            "executor": "composer"
        },
        "template": {
            "type": "typo3-cms-bundle",
            "package": "cpsit/project-builder",
            "version": "1.1.1"
        },
        "properties": {
            "project": {
                // ...
            }
        },
        "applied-steps": [
            "installComposerDependencies",
            // ...
        ]
    }
}
