Adjust initial gen_server_call_timeout

to prevent `amqp_connection:start/2` from logging a warning when we use default
values.

The default for `connection_timeout` is already 60000. When we don't explicitly
set it to a lower value, `amqp_connection:maybe_update_call_timeout/2` adjusts
it to 70000 and logs a warning message, which may appear unexpected, especially
for users upgrading to 3.8.10+ with no config changes.

This change addresses that problem by pre-adjusting it to 70000, making it safe
by default and ensuring our default values don't conflict with each other.
