Update Alamofire to v5

[crazytonyli]

Changes include:

• Updating WordPressKit to the trunk revision, which does not depend on Alamofire.
• Updating Alamofire, AlamofireImage, and AlamofireNetworkActivityIndicator to the latest versions.
• Replacing deprecated Alamofire API usages with new APIs.

I don't think we need AlamofireNetworkActivityIndicator, considering UIApplication.networkActivityIndicatorVisible has been deprecated and iOS doesn't even show a spinner in status bar any more (at least I can't find a way to make it).

Test Instructions

You can test AlamofireImage changes by verifying images in Reader and Posts list can be displayed.

PR submission checklist:

• I have completed the Regression Notes.

This Stack Overflow answer is useful in that it says "The deprecation message says: Provide a custom network activity UI in your app if desired."

Also, AlamofireNetworkActivityIndicator hasn't been updated since April 2020. I think it's safe to remove it in a dedicated PR. We can always revert if something goes wrong.
