Requests With Query Parameters With "+" Character Do Not Work

[Odoyle-Rules]

Describe the bug

When a user of our platform has an account with an email address with a "+" in it (e.g. bob+example@email.com), REST requests that have query parameters that use the email address do not work. Other REST requests where the same email is used in the body of the call are successful. Users with accounts on our platform that use the Android version of the Amplify library are just fine making the same calls with the "+" character in the email address in the query parameters.

I have tried encoding the query parameters and I get the same error from AWSAPIGateway. When I encode the query parameter, the error returned from AWS has the full URL and shows the decoded query parameters in the URL.

I found a related issue here: #3955

Steps To Reproduce

Make an HTTP request to an AWSAPIGateway endpoint using Amplify for Swift and include a string query parameter value with a "+" character in it.

Expected behavior

I need Amplify to treat this string as a string, encode it if necessary, but I need this request to make it to my endpoint.

The workaround for #3955 does not work in this case, I do not have a workaround. This is a big deal for customers with accounts created with emails containing +.
