Truncate commit summary on repo files table. (#22551) (#22552)

Backport #22551
There was an unintended regression in #21124 which assumed that
.commits-list .message-wrapper would only match the commit summaries on
/{owner}/{name}/commits/*. This assumption is incorrect as the
directory/file view also uses a .commits-list wrapper.

Rather than completely restructure this page this PR simply adjusts the
styling to again use display: inline-block; for #repo-files-table
.commit-list .message-wrapper

Fix #22360
