Migrate foundation website to Hugo

[juliaferraioli]

Summary of changes:

• Migrated foundation website to the Hugo static site generator following similar structure as conf.tlapl.us
• Used relearn theme as the theme from the conference website is deprecated
• Added a .gitignore appropriate for the site/repo
• Added a workflow to build and publish the site upon push
• Updated README with new file structure

I realize that this is a big change in one pull request but I don't think there's a graceful way to break it up. You can preview the site live (deployed through the workflow) at my fork.

The new site looks much nicer than the old (placeholder).

Thank you! A couple of questions for you @lemmy: do you prefer to have the reviewer merge or would you like me to? And do you have a preference towards rebase & merge or squash & merge? (I tend towards squash & merge just out of habit.)

@juliaferraioli Please do as you see fit. :-)
