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
