dashboard: remove accidental whitespace from C Repro cell
dashboard: remove accidental whitespace from C Repro cell

Commit 2f3b44ea4 ("dashboard: visualize stale repros") inadvertently
added a single space in the "<td class=repro>" tag.  This will break
tooling which relies on HTML scraping and pattern matching.  This
patch ensures the formatting is kept consistent whilst honouring the
author's true intentions.
