A Password protected version for Design Histories

[Nikolaos-Gkionis]

Currently working on a Home Office project for SC / DV level clearance and they don't want any Design Histories being open to the general public.

I have forked this repo and successfully updated the eleventy.config.js file to add this functionality.
The package.json has also been updated with a couple of requirements for this to work.
I have not raise a PR, as this will obviously need more of a discussion.

Granted, for 5$ a month on Heroku, you could add a different method, or for 19$ a month on Netlify you set up SSO.

However, this is 💯 free and open source.

Here's the repo: https://github.com/Nikolaos-Gkionis/design-history-password
