Fix: Update SDWebImage to comply with Apple's privacy manifest requirement (ITMS-91061)

[flymoonai]

Apple now requires SDWebImage to include a privacy manifest (PrivacyInfo.xcprivacy). SDWebImage added this in version 5.18.7.

This PR updates:

• SDWebImage: 5.15.5 → ~> 5.19
• SDWebImageWebPCoder: 0.11.0 → ~> 0.14

Tested: Verified that pod install resolves correctly and the project builds with SDWebImage 5.21.4 and SDWebImageWebPCoder 0.15.0.

The "0.0.1-alpha" build is a placeholder version for testing and is unrelated to the failure.
The root cause is a version mismatch of SDWebImage between the Podfile and Podfile.lock.
Before the patch lands, please update the Podfile.lock here first: https://github.com/lynx-family/integrating-lynx-demo-projects/blob/main/ios/HelloLynxObjc/Podfile.lock
