replace jekyll with astro

[levino]

I recently migrated one of my websites to astro. I think it is perfect for simple websites and "the new jekyll". Way better than nextjs because of simplicity and content collections.

I put this here as a basis for discussion, following @thomasdavis remarks.

I haven't used it, but been meaning to. So we might as well.

The plan was to also make reusable components so that any websites/tools for JSON Resume can just we use, but can abstract when actually needed.

I've always loved the theme/simplicity of the current homepage so I don't think the rebuild should focus on revamping it all too much. (mostly just the structure, the pages themselves can be a lot different)
