This PR is related to #2309. I added an optional `last_updated` field.
This new field represents the timestamp for when the post was last
updated. Consequently, the existing `date` metadata should now be
interpreted as the creation date of the post.
The formatting for displaying these dates has been standardized as
follows:
```text
Created: July 11, 2023 | Last Updated: April 14, 2024
```
For a practical implementation example, please refer to [this
post](https://torydeng.github.io/blog/2023/deploying-server/) on my
website, where I have applied these changes.

Any feedback is wellcome.
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
