Generate output for `project`/`build` health in machine-readable format

**Describe the solution you'd like**
New output format for `projectHealth` and `buildHealth`.

In order to support features like [Github Checks](https://docs.github.com/en/rest/checks?apiVersion=2022-11-28), we need the ability to see line-numbers and other metadata associated with files specifically.

In order to reduce the feature request, if we generated `errorformat` outputs, we could hook into tools like [@reviewdog/reviewdog](https://github.com/reviewdog/reviewdog).

**Describe alternatives you've considered**

I wrote up a github action with a python script to parse the `buildHealth.txt` file for outputs: https://github.com/Nava2/dependency-analysis-reviewdog-action. This works OK, but it is brittle and prone to errors as the formats change.

Another, better example than `errorformat` is probably using `sarif` ([Link](https://docs.oasis-open.org/sarif/sarif/v2.0/sarif-v2.0.html))

Start with the projectHealth and buildHealth outputs and compare the existing buildHealth.txt format with the requested machine-readable metadata. Review the errorformat and SARIF references, then define the supported format and verify that it exposes file line numbers and other metadata for GitHub Checks or reviewdog integration.
