fix(colorscheme): use explicit normal foreground in syntax groups

Browse Source 
Problem: Some core syntax highlight groups are cleared with intention to
  always be shown without additional highlighting. This doesn't always
  work as intended, especially with fallback mechanism of @-groups.
  Example: `Statement`/`Keyword` group shown in help code blocks
  (`@markup.raw`) is shown as bold (from `Statement`) cyan (from
  `@markup.raw`) instead of bold grey.

Solution: Explicitly use normal grey foreground in syntax groups where
  it was previously implicitly assumed.
