Fix Instagram widget not updating (v2)

[violetshine]

Remove SnapWidget since it seems to have become paid and stopped pulling updated from Instagram a long long time ago. Use Instagram's first-party embedding feature instead of a third-party service.

Redid this PR because of the Astro migration forcing me to delete my local clone of the repo and start all over again.

Fixes: #213

Oops, Astro does the importing a little bit differently than the old system. Fixed that and amended my commit.

It still does hint about the iframe being scrolling="no" if running npm run check locally because according to some HTML5 spec that should be done with CSS instead but it seems like Chrome still has not yet implemented the same in CSS 13 years later and expects it to be scrolling="no" even thoughscrolling is meant to be deprecated. Can't do anything about that, it's Google's problem to deal with.

Fixed
