fix(lexer): Only allow horizontal whitespace in frontmatter In writing up the reference for frontmatter, I realized that we probably shouldn't be accepting Unicode Line Ending characters between the code fence and infostring or trailing after the infostring or a code fence. In digging into the unicode specification we use for Whitespace, it divides it up into categories, so I'm deferring to what it says for horizontal whitespace for what should be used within a line. Note, I am leaving out support for Unicode Default Ignorable characters. I figure that can be discussed outside of this change within the reference and tracking issue. Fixes rust-lang/rust#145971 Frontmatter tracking issue: rust-lang/rust#136889
