Don't use ReadableStream as an asyncIterator (#5144)

# Description of Changes

Reverts part of #4561. Fixes an issue with
`ReadableStream[Symbol.asyncIterator]` not being defined on safari until
recently.

# Expected complexity level and risk

# Testing

- [x] Firefox <!-- Confirmed by @coolreader18 -->
- [x] Safari <!-- Confirmed by @joshua-spacetime --> (Run a web template
project in safari with `.withCompression('gzip')`)
