[pdt-dev] "The server does not support version 7.4 of the PHP Project sp

[Basil Mohamed Gohar <basilgohar@xxxxxxxxxxxx>]

I was exploring PDT's built-in server running features because I usually 
run at least one or two instances of a built-in server, whether it's the 
one started by Laravel's `artisan serve` command or the PHP 
command-line's one via `-S`.  However, after configuring my runtime 
based on the PHP executable that comes with Fedora (PHP 7.4.6) I got the 
following message when I attempted to add a new server:

"The server does not support version 7.4 of the PHP Project specification."

Someone had this same error message about one month ago and posted on 
the Eclipse subreddit (found via searching):

Can someone help me through this issue and how I can get this working, 
if at all?  Thanks!
