ERR_OSSL_UNSUPPORTED on crypto.verify

[mattjmatthias]

Having got this setup and running, I find when the lambda actually runs to verify a passkey, it fails with the error

Error: error:1E08010C:DECODER routines::unsupported
    at Verify.verify (node:internal/crypto/sig:230:24)
    at validateAssertionSignature (file:///var/task/index.mjs:61:22)
    at Runtime.handler (file:///var/task/index.mjs:27:42)
    at Runtime.handleOnceNonStreaming (file:///var/runtime/index.mjs:1173:29) {
  library: 'DECODER routines',
  reason: 'unsupported',
  code: 'ERR_OSSL_UNSUPPORTED'
}

Having looked into other implementations of webauthn, it seems surprising that no consideration of the different algorithms that are used is included in this code demo.
