[WebProfilerBundle] Small bugfix in CSS: don't make links bold.

If the CSS in your application has something like `a { font-weight: bold; }` to make links bold by default, they will also show up **bold** in the profilers toolbar, which doesn't look right. This patch explicitly sets the font-weight to 'normal', as it should be.
