Fixes

• Remove OpenSSL dependency - ashleygwilliams/pr515, geelen/i514

  If a release happens without an OpenSSL issue, does it really happen? In trying to run oranda build on a beta image for Cloudflare Pages, an end user discovered that we hadn't fully vanquished our dependency on OpenSSL. With this PR, we've made 100% sure we have.

• Allow schema key in oranda.json - Gankra, pr506

  To improve the user experience of configuring oranda, we error on unexpected keys in the oranda.json file- which will help people see typos and other mistakes. However, this checking was over-eagerly erroring when folks added a schema key so they could use VS Code's schema support. This PR makes an exception for users including the "non-functional" (in oranda) schema key.

• Add fallback to macOS Intel artifacts if Apple Silicon detected, but no artifacts found - Gankra, pr511

  Platform support and detection is slightly more complicated on Apple/macOS machines because Apple offers Rosetta2 which allows you to run binaries built for older Intel-based systems on the new Apple Silicon ones (but not vice versa). This PR updates the install widget's behavior to show artifacts built for Apple Intel-based systems if it detects an Apple Silicon system but cannot find any binaries built for Apple Silicon.

• Artifact table width on mobile - SaraVieira, pr505

  On mobile, the artifact table's width was forcing a scroll. We've updated the CSS to fix this!
