Cherry-pick docs commits to docs-v1.7.0 branch

[vincentfretin]

Description:

Changes proposed:

• Cherry-pick from master the docs changes that are valid for aframe 1.7.1

[vincentfretin]

This is to address aframevr/aframe-site#556
Also someone has to rewrite the introduction and hosting pages to remove glitch and mention stackblitz for dev, replit for prod or something else.

Thank you!

Can you please cherry-pick #5762 in the docs-v1.7.0 branch:

git checkout docs-v1.7.0
git cherry-pick 96e2f2ddcf5cf916bfd4116924383343d8ba0ad7
git push

and I think the doc build is triggered only on master? So we'll need a commit in master to trigger the rebuild of master and 1.7.0 documentation to trigger the commands https://github.com/supermedium/a-frobot/blob/4ce549b2fc83554a2f510590a254d073415d3535/lib/deployAframeSite.js#L26-L40
the npm run bumpdocs takes care of updating master and latest release currently docs-v1.7.0 branch.

I still see glitch section on master doc https://aframe.io/docs/master/introduction/hosting-and-publishing.html I remember you once said you ran the build command manually on the aws instance, but that was before we update all the code to support latest node. I thought you put back the aframe bot to do it automatically since then, that's not the case?

All docs are deployed manually at the moment. no bots
