Update wrapping-unwrap.mdx

What I did

It is possible to unwrap data without authentication in Vault. I've added an example in the documentation with a curl request.

How to check

curl -s -H "X-Vault-Wrap-TTL: 600" -H "X-Vault-Token: 12345" --request POST -d '{"msg": "another_success"}' http://127.0.0.1:8200/v1/sys/wrapping/wrap | jq -r '.wrap_info.token'

curl -s -X POST -H "X-Vault-Token: hvs.CAESICWi76JlYaIuEw6gUUhoonSHV6s9AEEe6tP8yToFrSyXGh4KHGh2cy5taEtROGZBYWZqMmxaTXFJTUIyZ3dYUUE" http://localhost:8200/v1/sys/wrapping/unwrap | jq '.data'
{
  "msg": "another_success"
}
