Motivation and Context

Resolves #20663

Currently transporter class tries to decode Base64 not only encoded key but also not encoded key (e.g. loaded token from Spaceship::ConnectAPI.token). It causes #20663

Description

Testing Steps

Test with api_key like below

pilot(
  api_key: { 
    key_id: "xxx", 
    issuer_id: "xxx", 
    key: "E ... ==", # base 64 encoded key
    is_key_content_base64: true,
  }
)

# and

pilot(
  api_key_path: "api.json"
)

'''
// api.json
{
  "key_id: "xxx", 
  "issuer_id": "xxx", 
  "key": "E ... ==", # base 64 encoded key
  "is_key_content_base64": true,
}
'''

@crazymanish @AliSoftware Could you take a look it with #20662? It is bug affect to pilot action 😢

[freddi-kit]

it is added by https://github.com/fastlane/fastlane/pull/20631/files#diff-ba9086d4da8fe68c8c84efaffba0f85f39d64b5a1c08b0a6db13360783e10007R25 but now no longer necessary

[AliSoftware]

I haven't tested it (I don't have an API Key around on my personal Mac from where I'm reviewing this) but code logic looks good to me 👍

[freddi-kit]

@AliSoftware Thanks, I fixed!

I've been dealing with the exact same issue #20663 since the release of Xcode 14 on Azure Devops. I'm glad you've found the root cause and fixed it. Can't wait to merge & release it already! Thanks!🥇

Hey @freddi-kit, what can we do to move this forward?

[freddi-kit]

Please wait fastlane member's action 🙇 I cannot do anything more

@AliSoftware, sorry to be a bother, but do you know if anyone on the fastlane team is planning on taking a look at this PR? This fixes what seems to be a blocking issue for me using Xcode 14 as well. It would be greatly appreciated ❤️
