[feature][blog] create a progress bar for when scrolling

[jonny-wg2]

As shown here https://zapier.com/blog/use-openai-gpt-3-for-content/ I noticed that there is a progress bar. Sort of cool.

In a quick google search I found https://codyhouse.co/ds/components/info/reading-progressbar - which looks like a good option.

So leveraging this for wgtwo.com/blog/articlexyz, and changing the color to match our accent blue that is used for the pills could be a nice feature and engagement for the blogs.

Took a shot at this with a simple npm package I found: https://github.com/working-group-two/wgtwo.com/pull/402

The component you found unfortunately costs money x)

Implemented and works great!
