[WIP] add ahead/behind commit count for branches. Something is currently broken here.

  // FILE.TS
  const flatFilesData = flatFiles(reposData)
  console.log(flatFilesData.filter(entry => entry.file.includes('njk')))
  eleventyConfig.addTemplate(
    'repos/file.11ty.js',
    htmlPage(reposConfiguration, eleventyConfig, fileJsTemplate),

  const result = await exec(command)
  let files = result.stdout.split("\n").filter(item => item.length > 0 && item != ".")
  if (branchName === 'main') {
    console.log(files)
  }
  // TODO: this could be better. This is adding each sub-path of a file to a set, so that
  // we don't wind up with repeats, and then converting that back into an array. E.g. if
  // we have two files:

    "noImplicitAny": false,
    "module": "node18",
    "target": "es6",
    "lib": ["esnext", "dom"],
    "allowJs": true,
    "outDir": "dist"
  },
