broken links in new playground (+ suggestion)

[pchampin]

https://json-ld.org/playground/next/ points to a number of "other related playground"

• Classic JSON-LD 1.0 Playground (https://json-ld.org/playground/next/1.0/) is broken (should be https://json-ld.org/playground/1.0/)
• RDF Distiller (http://rdf.greggkellogg.net/distiller) is currently(?) gone 😢
• may I suggest to add SoWasm https://champin.net/2023/sowasm/ 😇

Yep. On my list...and partially done locally, but thank you for the issue!
