Cannot set RSAPublicKey for Consumer By JWTAuth.Create()

[yuta-takahashi-jpc]

Issue Descript

using: kong/go-kong v0.59.1

jwtAuth := kong.JWTAuth {
  Key: "http://hoge.fuga.com",
  Algorithm: "RS256",
  RSAPublicKey: url.QueryEscape("------BEGIN PUBLIC KEY-----\r\n%s\r\n-----END PUBLIC KEY-----", pubKey)
}

client.JWTAuth.Create(ctx, consumer.ID, jwtAuth) // failed

error message is

2 schema violations (failed conditional validation given value of field 'algorithm'; rsa_public_key: invalid key)

in Kong docs, jwt plugin needs Content-Type: application/x-www-form-urlencoded.
but Content-Type: application/json was given to httpclient in go-kong, I think this is the cause of the problem.

any way can I set Public key to consumer by go-kong?

thank you.
