Issue: Error message about code signing when running `flutter build ipa` is confusing
Labels: platform-ios,tool,t: xcode,a: build,P2,team-tool,triaged-tool

While investigating https://github.com/flutter/flutter/issues/148277, I tried running `flutter build ipa` on a new Flutter app. The tool fails with this output

```
andrewkolos-macbookpro:hello_world andrewkolos$ flutter build ipa

Archiving com.example.helloWorld...
Automatically signing iOS for device deployment using specified development team
in Xcode project: KW457W2YCN
Running Xcode build...                                                  
Xcode archive done.                                          2.9s
Failed to build iOS app
Error (Xcode): No profiles for 'com.example.helloWorld' were found: Xcode
couldn't find any iOS App Development provisioning profiles matching
'com.example.helloWorld'. Automatic signing is disabled and unable to generate a
profile. To enable automatic signing, pass -allowProvisioningUpdates to
xcodebuild.

It appears that there was a problem signing your application prior to
installation on the device.

Verify that the Bundle Identifier in your project is your signing id in Xcode
  open ios/Runner.xcworkspace

Also try selecting 'Product > Build' to fix the problem.
Encountered error while archiving for device.
andrewkolos-macbookpro:hello_world andrewkolos$ open ios
```

The noteworthy part about this is

```
Verify that the Bundle Identifier in your project is your signing id in Xcode
  open ios/Runner.xcworkspace
```

I might just be missing some prerequisite knowledge here, but does this even make sense? Aren't signing identities and bundle identifiers completely disjoint concepts?

Moving on, I was able to get past this issue by opening the workspace, selecting the Runner project, selecting the Signing & Capabilities tab, and then choosing a valid Team under the Signing section.

Interestingly, if I select None as the Team and run `flutter build ipa`, I get a much better error message that more or less describes the solution I had to figure out on my own:

```
andrewkolos-macbookpro:hello_world andrewkolos$ flutter build ipa

Archiving com.example.helloWorld...

════════════════════════════════════════════════════════════════════════════════
Building a deployable iOS app requires a selected Development Team with a 
Provisioning Profile. Please ensure that a Development Team is selected by:
  1- Open the Flutter project's Xcode target with
       open ios/Runner.xcworkspace
  2- Select the 'Runner' project in the navigator then the 'Runner' target
     in the project settings
  3- Make sure a 'Development Team' is selected under Signing & Capabilities >
  Team.
     You may need to:
         - Log in with your Apple ID in Xcode first
         - Ensure you have a valid unique Bundle ID
         - Register your device with your Apple Developer Account
         - Let Xcode automatically provision a profile for your app
  4- Build or run your project again

For more information, please visit:
  https://flutter.dev/docs/get-started/install/macos#deploy-to-ios-devices

Or run on an iOS simulator without code signing

I would have expected these instructions to have been included in the output from my first attempt to run `flutter build ipa`.
