Fix overflowing content in action run log (go-gitea#31842)

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.

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
