Subject: [PATCH] fix: define `excludeBkgColor` for `theme-dark`

Define `excludeBkgColor` for `theme-dark` to fix invalid CSS
for gantt diagrams.

All the other themes defined this to '#eeeeee', but I thought that
was a bit too bright in a dark theme, so instead I set it to
`darken(this.sectionBkgColor, 10);`.
