Setup: Update error message for composer dependencies check

Browse source 
== Why ==

While psr/log represents our original an first use of Composer,
this is nowadays "just" another dependency among many. It does not
justify or help understand what to do next.

== What ==

Use the same "external libraries" terminology, as on mediawiki.org.

== History ==

* 2014 (Ie66794441): Add first ever Composer dependency (psr/log)
* 2015 (Ie47467657): Add LoggerFactory with check for missing Composer
                     dependency, to address a then-common issue.
* 2015 (Ib60261237): Move check earlier, to WebStart.
* 2017 (I633a6ff23): Move check earlier, to Setup.
* 2021 (Ia81903fb2): Remove redundant exit(1).
* 2025 (I6050ec4ca): Replace deprecated E_USER_ERROR.
