FIX webwork startup crash, WEBWORK_ROOT_URL typo

Webwork tries to start and dies due missing SQL::Abstract::Classic lib:

app-1        | Base class package "SQL::Abstract::Classic" is empty.
app-1        |     (Perhaps you need to 'use' the module which defines that package first,
app-1        |     or make that module available in @inc (@inc contains: /opt/webwork/webwork2/lib /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.38.2 /usr/local/share/perl/5.38.2 /usr/lib/x86_64-linux-gnu/perl5/5.38 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl-base /usr/lib/x86_64-linux-gnu/perl/5.38 /usr/share/perl/5.38 /usr/local/lib/site_perl).

app-1        | Compilation failed in require at (eval 426) line 1.

WEBWORK_ROOT_URL definition in Dockerfiles used two colons before the
port when it's supposed to be only 1.

Also deleted version line from docker-compose.dist.yml, as I get a
warning message that `version` is obsolete.
