wctaiwan 0f4a775659 Tweak error message for missing composer dependencies
It wasn't obvious to me that the mediawiki.org link actually pointed
to specific instructions for resolving the error, as opposed to
just telling the user to search on mediawiki.org. Try to make this
a bit more obvious.

/**
* The setup for all MediaWiki processes (both web-based and CLI).
*
* This file must be included by all entry points (such as WebStart.php and doMaintenance.php).
* - The entry point MUST do these:
* - define the 'MEDIAWIKI' constant.
* - define the $IP global variable.
* - The entry point SHOULD do these:
* - define the 'MW_ENTRY_POINT' constant.
* - display an error if MW_CONFIG_CALLBACK is not defined and the
* file specified in MW_CONFIG_FILE (or the $IP/LocalSettings.php default)
* does not exist. The error should either be sent before and instead
* of the Setup.php inclusion, or (if it needs classes and dependencies
* from core) the error can be displayed via a MW_CONFIG_CALLBACK,
* which must then abort the process to prevent the rest of Setup.php
* from executing.
*
* It does:
* - run-time environment checks,
* - load autoloaders, constants, default settings, and global functions,
* - load the site configuration (e.g. LocalSettings.php),
* - load the enabled extensions (via ExtensionRegistry),
* - trivial expansion of site configuration defaults and shortcuts
* (no calls to MediaWikiServices or other parts of MediaWiki),
* - initialization of:
* - PHP run-time (setlocale, memory limit, default date timezone)
* - the debug logger (MWDebug)
* - the service container (MediaWikiServices)
* - the exception handler (MWExceptionHandler)
* - the session manager (SessionManager)
* - complex expansion of site configuration defaults (those that require
* calling into MediaWikiServices, global functions, or other classes.).
