Adds a copy to clipboard button using Clipboard.js
Optional support for defining which lines to copy out of the code box.
Adds styling and anchor links to the line numbers
Adds support to link to line number anchors inside tabs
Removes line numbers from tables (no user impact, changes styling and JS element targeting)
Makes the top NAV not sticky. This is required to make the line number anchors work. Otherwise the line number linked to will go under the navbar and not be in view. Fixing this with a sticky nav is a very large lift (for me). Also note, the side bars are still sticky.
Removes clipboard scsss files. All clipboard related styles are merged into code-theme-base.scss
Also applies Hugo caching fixes that can cause the stylesheet not to load in local dev (discovered in this PR)
This completely redesigns the docs and moves them to a new domain docs.crossplane.io and hosting on Netlify.
This creates a custom Hugo theme affectionally called `Geekboot` based the work of both [Geekdoc](https://geekdocs.de/) and [Bootstrap](https://github.com/twbs/bootstrap/tree/main/site).
[Lighthouse testing on desktop](https://pagespeed.web.dev/report?url=https%3A%2F%2Fdocs.crossplane.io%2Fv1.10%2F&form_factor=desktop) gives the site a 100/100 in performance and best practices, 90/100 in accessibility and 92/100 in SEO.
Besides new layout and colors other new user-facing features include:
* Dark mode
* Fully responsive design and mobile ready
* Automated webp image conversion and optimization as well as lazy loading
* Tabs
* Alerts and hint boxes
* Foldable/hide long outputs
* Linkable anchors inside tabs
* Improved code boxes with line numbers
* Adds support for docs.crossplane.io/latest
* Right hand page table of contents
* Improved text readability
Infrastructure improves:
* Uses [Bootstrap](https://getbootstrap.com/) to dramatically simplify styling and site development
* Prefetch links on hover using [instant.page](https://instant.page/)
* Highly optimized CSS using PostCSS and [PurgeCSS ](https://purgecss.com/) without requiring users to install additional tools
* Minimizes the use of JavaScript and bundles scripts with [Webpack](https://webpack.js.org/) to optimize load times
* Massive improvement of SCSS/CSS organization and overrides improving the development process for stylesheet changes
* Optimizes existing SVGs and converts all other template images to webp
* Minification on production builds to further reduce page sizes
This also bumps the `Makefile` Hugo version to [0.107.0](https://github.com/gohugoio/hugo/releases/tag/v0.107.0) to pick up build improvements related to code syntax highlighting, improving builds about about 20-30% in unscientific testing.
