Updates

Not included:

• Bootstrap v5
• Phoenix Changes in Controllers / Layouts (like HTML modules instead of View modules; causes dialyzer issues)
• We should probably get rid of etso. It does not seem to be maintained anymore.

I'm tempted to merge this as is, since I had a branch that was doing the same. There's a bit more work to do I believe besides what's in this PR, so I would take the work you've done here and build upon it.

As for etso, my thoughts here are not that is unmaintained, though that may be true at this point in time, but rather we need to move as much as we can into static site portion of the site (nimble publisher is what's on my mind atm).

@starbelly I have no issues with merging this as is. For sure test yourself if this breaks anything before you deploy to prod, but otherwise that should be fine.

For the future I was thinking to use Jekyll in combination for Plug.Static to serve the static pages.

The reason why I would chose Jekyll over something like nimble publisher is:

• We have other websites using an EEF theme built with jekyll
• Jekyll can do more than just having one type of posts. With _data we should be able to build nice interconnected data structures for WGs, members, blogs etc.
• If we ever move of the dynamic parts like the Slack invites, we can just serve this with GitHub directly.
