Default value of ssh_client_alive_interval is inconsistent with what documentation says

[giordano]

Description

Documentation of ssh_client_alive_interval claims that the default is 600 seconds

ansible-collection-hardening/roles/ssh_hardening/README.md

Lines 114 to 118 in cec9c99

	- `ssh_client_alive_interval`
	- Default: `600`
	- Description: specifies an interval for sending keepalive messages.
	- Type: str
	- Required: no

This is inconsistent with what the actual code, where ssh_client_alive_interval defaults to 300 seconds:

ansible-collection-hardening/roles/ssh_hardening/defaults/main.yml

Line 64 in cec9c99

ssh_client_alive_interval: 300 # sshd

Expected Behavior

Code and documentation should be consistent. If I had to choose, I'd prefer a longer timeout, so favouring what the documentation says, I'm finding the default value of 300 seconds very short (I know I can change it, just reporting the experience of dealing with timeouts every 5 minutes).

Thanks for spotting this, @giordano! 300 is the current and correct default.

Since it's really easy to change it in your playbook, the default is unlikely to change.

I fiexd the docs in #703
