Added GitHub action to do axe accessibility tests with [axe
cli](https://github.com/dequelabs/axe-core-npm/tree/develop/packages/cli).
I believe it is best by default to let this be run only manually, since
fixing some of the issues are not straightforward (I haven't fixed them
all for this template yet).

Added GitHub action to check for broken links in repo before commit,
ignoring files with liquid tags since these were not yet processed and
also README since some sites created from this template doesn't have
valid urls anymore. Fixed some broken links in repo.

summary:
- adds prettier formatter configuration
- formats the entire repo using prettier, ignoring minified files
(`*.min.css`) and heavy generated html
- changes extensions of all `.html` files to `.liquid`, which is more
correct and necessary for prettier to work correctly
- replaces "%-" and "-%" with just "%" — manual liquid formatting using
minus signs is superfluous since we are compressing and minifying the
code anyway
- adds CI action for running prettier check on PR and pushes to master
I decided to break the README file into different ones to declutter it
from the main page. Also adding some more explanation on the structure
of the template. Tackling #2032 and #2033

Updated README to explicitly tell how to proceed on creating your own
version based on this template. Also removed the video tutorial since it
was for an older version, recommending to fork the repo and it was
missing the `--lsi` parameter from jekyll command. Also was not using
docker, the current recommended way.

Tackled #1329 with [PurgeCSS](https://purgecss.com/).
Being talking with @varuniyer about using
[jekyll-uncss](https://github.com/episource/jekyll-uncss) to reduce css
file sizes by ditching unused classes. This approach have 3 main
problems:
1 - have some limitations as pointed
[here](https://github.com/alshedivat/al-folio/issues/1329#issuecomment-1546517327)
2 - last update to
[jekyll-uncss](https://github.com/episource/jekyll-uncss) was about 3
years ago, so it might have a few issues
3 - [uncss](https://github.com/uncss/uncss) haven't seem a new release
in a while, currently [lacking
maintenance](https://github.com/uncss/uncss/issues/459), and using some
deprecated libraries as seem here:
```
npm install -g uncss
npm WARN deprecated request-promise-native@1.0.9: request-promise-native has been deprecated because it extends the now deprecated request package, see https://github.com/request/request/issues/3142
npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm WARN deprecated w3c-hr-time@1.0.2: Use your platform's native performance.now() and performance.timeOrigin.
npm WARN deprecated uuid@3.4.0: Please upgrade to version 7 or higher. Older versions may use Math.random() in certain circumstances, which is known to be problematic. See https://v8.dev/blog/math-random for details.
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
```
I thought about giving PurgeCSS a go, since it has been more [actively
maintaned](https://github.com/FullHuman/purgecss), but
[jekyll-purgecss](https://github.com/mhanberg/jekyll-purgecss) haven't.
For this, I needed to change to use some local libraries instead of
getting them via CDN. The good news is that it is quite effective in
reducing css file sizes. Comparing dir sizes with `du -hs
_site/assets/css/`:
| current | minify | PurgeCSS | PurgeCSS + minify |
| ------- | ------ | -------- | ----------------- |
| 1,1M | 988K | 456K | 420K |
