chore!: join IDE and editors into same section (#7065)
* chore!: join editors into section `IDE and editors`

This homogenize the place where are organized the IDE and editors like Vim, Emacs, Visual Studio, Visual Studio Code, Eclipse, IntelliJ... into the same section.

Emacs Lips is a language per sé. so apply and add some crosslinks #5535 in order to reference editors.

Moved books in `-langs.md` now are in `-subjects.md` since editors are language agnostic, I think.

Complete this moved resources with author, formats and notes
