Fix Remoted IT: test_agent_communication

[juliamagan]

Description

After the review made in #3060, we have seen that two tests of test_agent_communication were failing consistently:

• test_shared_configuration.py
• test_agent_version_shared_configuration_startup_message.py

After investigating the errors we have concluded that the error is here:

wazuh-qa/deps/wazuh_testing/wazuh_testing/remote.py

Lines 634 to 637 in 21a493b

	for _ in range(5):
	# send some keep alive messages until manager push the new group configuration
	sender.send_event(agent.keep_alive_event)
	time.sleep(1)

Where 5 keep-alives are sent every second. However, the correct behavior to simulate would be to send keep-alives every 10 seconds, which is the default configuration.
