WEBRTC-XXX - Ticket title

Please provide a summary of the change / issue with a proper context.

👴 👶 Behaviors

Before changes

• The info.plist was included in the Package.swift file, causing Xcode to throw the following error:
  "public headers ("include") directory path for 'TelnyxRTC' is invalid or not contained in the target"
• This error prevented the SPM package from resolving/loading correctly.

After changes

• The info.plist has been excluded from the Package.swift file.
• Manually tested and confirmed that the package resolves without an error now.
• Xcode no longer throws the "public headers ("include") directory path for 'TelnyxRTC' is invalid or not contained in the target" error.

TODO

I opened this PR three days ago to fix the SPM package issue in the latest SDK release. Is there any update on when it might be reviewed?
