Fix "See Podspecs" URL on Cocoapods.org website

[ezefranca]

See Podspecs link on the website are broken.

Example:

https://github.com/CocoaPods/Specs/blob/master/Specs/[%229%22,%20%22c%22,%20%22c%22,%20%22AppLovinSDK%22,%20%3CPod::Version%20version=12.1.0%3E]/AppLovinSDK.podspec.json

Should be

https://github.com/CocoaPods/Specs/blob/master/Specs/9/c/c/AppLovinSDK/12.1.0/AppLovinSDK.podspec.json

https://github.com/CocoaPods/cocoapods.org/assets/3648336/4f8106f7-bcf5-475e-a634-5aeb40e49394

This PR updates the or_podspec_url logic to fix this.
