Flowchart text color (#340)

* Update CSS

* STY: Remove inline formatting

From local testing it appears that the CSS overrides the inline style, i.e. the color directive could have been set to purple #800080 and it would still appear as #222 (off-black) or whatever is defined in cusstom.css for mermaid text.

So I removed this so that it is clear that the flowchart text color is derived from the CSS file
