Wrong Info.plist generated by disableAppTransportSecurity

**Description:**
The Info.plist generated by the command `ionic capacitor run ios -l` is incorrect and prevents Xcode from building the app if the key `NSAppTransportSecurity` is already defined.
The issue started after updating to Xcode 15.2. Previous versions like 14 work as expected.

**Steps to Reproduce:**
1. Create an ionic app with iOS support
2. Add the following configurations to the Info.plist file:

```
NSAppTransportSecurity

NSExceptionDomains

facebook.com

NSIncludesSubdomains

NSThirdPartyExceptionRequiresForwardSecrecy




```
3. Run the app with the command ionic capacitor run ios -l.

**Output:**
The Xcode build fails with the following error:
```
[capacitor] error: unable to read property list from file: /Volumes/Projects/xxx/ios/App/App/Info.plist: The operation couldn’t be completed. (XCBUtil.PropertyListConversionError error 2.) (in target 'App' from project 'App')
```

**My `ionic info`:**

```
Ionic:

Ionic CLI : 6.20.9
Ionic Framework : @ionic/react 6.7.5

Capacitor:

Capacitor CLI : 6.0.0
@capacitor/android : 6.0.0
@capacitor/core : 6.0.0
@capacitor/ios : 6.0.0

Utility:

cordova-res : not installed globally
native-run : 2.0.1

System:

NodeJS : v20.13.1 (/Users/xxxx/.nvm/versions/node/v20.13.1/bin/node)
npm : 10.5.2
OS : macOS Unknown
```

**Other Information:**
The problem is in the disableAppTransportSecurity method in https://github.com/ionic-team/ionic-cli/blob/%40ionic/cli%407.2.0/packages/%40ionic/cli/src/lib/integrations/capacitor/ios.ts

Line 45 adds the true value without adding NSAllowsArbitraryLoads key.

As a workaround I added the default values to the Info.plist in the NSAppTransportSecurity dict:
```
NSAllowsArbitraryLoads

```
