Single SSO Mode

[Valinwolf]

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
When is SSO only mode and only one SSO is configured, you still have to click an extra button.

Describe the solution you'd like
A clear and concise description of what you want to happen.
Either a setting for "Single SSO Mode" -or- when only one SSO is configured and "SSO only mode" is on, the login page is skipped on the click of the login button and it goes directly to the configured SSO.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
Creating a fork and adding the feature myself, until I realized even though I know PHP twig is nearly it's own language and I was definitely lost in the sauce and eventually threw in the towel.

I don't know how helpful this would be, but in LoginSocialsComponent.php could have a function for checking if only one SSO is configured:

public function singleSSO(): bool
{
    $ssos = array(googleEnabled(), discordEnabled(), facebookEnabled(), githubEnabled(), privacyPortalEnabled(), keycloakEnabled(), simpleloginEnabled(), zitadelEnabled(), authentikEnabled(), azureEnabled());
    $counts = array_count_values($ssos);
    return if($counts[true]==1);
}

Some pseudo-code for the end of login.html.twig could maybe be:

{% if mbin_sso_only_mode() and component('login_socials')->singleSSO() %}
<script type="text/javascript">
$('.social > .btn').click();
</script>
{% endif %}

but I have no idea how twig works, so I wouldn't know if that is even possible.
