Update books page (add Horstmann, update FPiS, reshuffle) (scala#2921)

* add Scala for the Impatient back to the books page

it used to be there, but was removed (in scala#1706) because it
had fallen out of date. but there's a Scala 3 edition now.

* shorten intro text on books page

* books: update FPiS info

* remove some outdated info, incidentally fixing 404

* bump bundler version and update Gemfile.lock

* review feedback

 "Functional programming (FP) is a style of software development emphasizing functions that don't depend on program state... Functional Programming in Scala is a serious tutorial for programmers looking to learn FP and apply it to the everyday business of coding. The book guides readers from basic techniques to advanced topics in a logical, concise, and clear progression. In it, you'll find concrete examples and exercises that open up the world of functional programming."
