Remove abandoned and unused php-http/* dependencies (#1117)

`php-http/message-factory` has been replaced by `psr/http-factory` and is now abandoned.
`php-http/message-factory` was added in 8d37f7a as part of updating to PHP 8.1.
`php-http/message-factory` is not currently being used by our code.
`php-http/message` is not currently being used by our code.

Remove `php-http/message-factory` and `php-http/message` as a root dependency with:
```
docker run --rm -it -v $PWD:/app -u $(id -u):$(id -g) composer:2.9.2 --ignore-platform-req=ext-pcntl remove php-http/message-factory php-http/message
```
