[Documentation request] Add apache2 configuration template in documentation

[InitialCrow]

Hello
I installed taiga threw taiga-docker and all was good except for this web socket the nginx conf work perfectly, but my taiga is on an apache2 environment and I don't want to install nginx just for one soft.

So I use since 8 months now and after last update I feel taiga work slowly than usually.
In fact, I had trouble with websocket since beginin installation, taiga can't connect on the websocket SO after much research and test I make an apache2 configuration for who works perfect I suggest putting it on documentation below nginx setup in taiga-docker that its with ssl

<VirtualHost *:443>
        #set owner 
        ServerAdmin admin@domain.com
        ServerName domain.com #where taiga is accessible
        SSLEngine On # enable ssl
        
        #set certificate (lets encrypt here)
        SSLCertificateFile /etc/letsencrypt/live/project.initialcrow.com/cert.pem
        SSLCertificateKeyFile /etc/letsencrypt/live/project.initialcrow.com/privkey.pem
        SSLCertificateChainFile /etc/letsencrypt/live/project.initialcrow.com/chain.pem
	
        #prepare proxy for websocket
	RewriteEngine on #enable url rewriting
  	RewriteCond %{HTTP:Upgrade} websocket [NC] #detect websocket header
  	RewriteCond %{HTTP:Connection} upgrade [NC]  #detect websocket header
  	RewriteRule /(.*) ws://localhost:9000/$1 [P,L] #rewrite for websocket (wss)

  	# Reverse Proxy configuration
  	ProxyPass / http://localhost:9000/
  	ProxyPassReverse / http://localhost:9000/    
    	
       # Logs and other configurations
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>
