Pass along arguments to underlying `get` method in `follow_redirect!` (#33299)

* Allow get arguments for follow_redirect

Now all arguments passed to `follow_redirect!` are passed to the
underlying `get` method. This for example allows to set custom headers
for the redirection request to the server.

This is especially useful for setting headers that may, outside of the
testing environment, be set automatically on every request, i.e. by a
web application firewall.

* Allow get arguments for follow_redirect
