feat(plugin-lighthouse): add lighthouse runner

[BioPhoton]

This PR wraps lighthouse core functionality exported as ESM with a PluginRunner for the @code-pushup/lighthouse-plugin package.

It aims to leverage all functionality directly over reusing their ESM exports instead of using the CLI.
This is less code to maintain as well as faster to execute and more scalable in terms of process arguments.

Changes included in this PR:

• plugin options mirroring runLighthouse, the core functionality of lighthouse. The following arguments are defined: url, flags and config.
• a getRunner is implemented to get a lighthouse runner receiving the url, flags and config arguments
  • Parts of the functionality of lighthouse CLI are excluded: all commands that don't produce a report, latern data logic.
    The user is informed about missing implementations if by accident provided over the CLI flags or config object
• additional helper to generate and validate the used flags and config object
• added CONTRIBUTING.md to document setup and debugging of Lighthouse
• setup CI for Lighthouse path configuration on windows

Follow up PR:

• I this refactoring into a new PR Custom matcher for ui logger #552

Note

There is one thing left, I want to have the env variable only set for Windows in the CI.

References:

• I created a docs to describe debugging of Lighthouse
