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
