rustdoc: #13771: Make html links inside paragraphs more readable

All links inside docblocks will have their color set to `#4e8bca` (a
light blue color to contrast against the black text). This color also
offers a visible contrast from the surrounding text if viewed as
grayscale, making it suitable for accessability.

Docblock links will also be underlined when hovered over.
