v9.2.5-alpha.5 LH config + about page (#16)

* fix: Lighthouse plugin config and about page file links

  1. Lighthouse plugin config

    - set `fail_deploy_on_score_thresholds = "true”` in `[plugins.inputs]`
      to get some of the old behavior back. mastodon discussion:
      https://mastodon.social/@rdela/112208080966164909

    - PR 588 netlify/netlify-plugin-lighthouse#588
      Looks like a bunch of the config options and behavior changed
      and then netlify disabled issues

    - netlify-plugin-lighthouse is now in maintenance(-only) mode
      https://github.com/netlify/netlify-plugin-lighthouse/blob/main/CONTRIBUTING.md
      https://fosstodon.org/@eleventy/112208087737676821

    - explain lowering of seo failure threshold due to `x-robots-tag: noindex`
      header set on deploy previews

  2. about page file links

    - these worked in README but needed full URLs to trunk branch for the site

 In addition to Base Blog’s killer features and Eleventy 3’s bundler-free [ESM](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules) support, eleventeen sports a novel new visual experience we call [Rainbow Mode™](https://github.com/rdela/eleventeen/pull/1), powered by [Chromagen](https://github.com/famebot/chromagen), the color scheme generator we publish under the [Famebot](https://github.com/famebot) organization. Our homegrown Rainbow Mode is wholly distinct from and not to be confused with Emacs [rainbow-mode](https://elpa.gnu.org/packages/rainbow-mode.html), which “sets background color to strings that match color
 names.” We posit a third color scheme preference in addition to light and dark “modes,” rainbow.
 
-Here in the world of eleventeen, rainbow is the default. But we acknowledge not all sites are a match for Rainbow Mode, and still want those sites to enjoy the rest of what eleventeen has to offer, so [v9.2.3-alpha.5](https://github.com/rdela/eleventeen/releases/tag/v9.2.3-alpha.5), adds a `mono` option to [`_data/metadata.js`](_data/metadata.js) in [PR #13](https://github.com/rdela/eleventeen/pull/13) that will disable Rainbow Mode if you set it to `true`. `mono` is `false` by default, on purpose, because it beats making people set an option called `rainbow` to `false` and might make the current  {% raw %}`{%- if not metadata.mono %}`{% endraw %} template logic in [`_includes/layouts/base.njk`](_includes/layouts/base.njk) a little more resilient.

 You can see mono enabled at [mono.eleventeen.blog](https://mono.eleventeen.blog). Try toggling light and dark mode using devtools, there are links to how at the bottom to [chromagen.io](https://chromagen.io/).
