Fix overflowing content in action run log (#31842) (#31853)

Backport #31842 by @Adrian-Hirt

When a long line with characters such as dots is returned by a step in
an action (e.g. by the output of the Ruby on Rails test runner), it
overflows the log container, causing the page to scroll sideways (see
first screenshot):

This PR adds the CSS `overflow-wrap: anywhere;` to the
`.job-step-section .job-step-logs .job-log-line .log-msg` selector,
which causes such lines to wrap as well (see second screenshot in which
the line wraps nicely):
