Both string and bytes literals may optionally be prefixed with a letter 'r' or 'R'; such strings are called raw strings

I don't think that it is a correct wording. You cannot call rb'' as a "raw string", it is called "raw bytes". Or "raw bytes literal". Just like the docs docs in the next paragraph:

The 'rb' prefix of raw bytes literals has been added as a synonym of 'br'.

I propose to fix this by using this phrase:

Both string and bytes literals may optionally be prefixed with a letter 'r' or 'R'; such objects are called raw strings and raw bytes respectively.
