User guide lists not all of the libraries shipped with GHC

Summary

GHC User guide doesn't list all of the libraries that GHC ships with itself

Steps to reproduce

When looking into libraries that get installed with GHC e.g. using ghc-pkg in Stack with GHC resolver list of libraries shown:

$ stack exec --resolver=ghc-8.6.4 -- ghc-pkg list
/home/qrilka/.stack/programs/x86_64-linux/ghc-tinfo6-8.6.4/lib/ghc-8.6.4/package.conf.d
    Cabal-2.4.0.1
    array-0.5.3.0
    base-4.12.0.0
    binary-0.8.6.0
    bytestring-0.10.8.2
    containers-0.6.0.1
    deepseq-1.4.4.0
    directory-1.3.3.0
    filepath-1.4.2.1
    ghc-8.6.4
    ghc-boot-8.6.4
    ghc-boot-th-8.6.4
    ghc-compact-0.1.0.0
    ghc-heap-8.6.4
    ghc-prim-0.5.3
    ghci-8.6.4
    haskeline-0.7.4.3
    hpc-0.6.0.3
    integer-gmp-1.0.2.0
    libiserv-8.6.3
    mtl-2.2.2
    parsec-3.1.13.0
    pretty-1.1.3.6
    process-1.6.5.0
    rts-1.0
    stm-2.5.0.0
    template-haskell-2.14.0.0
    terminfo-0.4.1.2
    text-1.2.3.1
    time-1.8.0.2
    transformers-0.5.6.2
    unix-2.7.2.2
    xhtml-3000.2.2.1
/home/qrilka/.stack/snapshots/x86_64-linux-tinfo6/ghc-8.6.4/8.6.4/pkgdb
    (no packages)
/home/qrilka/.stack/global-project/.stack-work/install/x86_64-linux-tinfo6/ghc-8.6.4/8.6.4/pkgdb
    (no packages)

differs from what you see in the user guide for 8.6.4 - https://downloads.haskell.org/~ghc/8.6.4/docs/html/users_guide/8.6.1-notes.html#included-libraries Namely the following libraries are not listed in the guide: ghc-boot-th, ghc-heap, libiserv, pretty, rts, stm and terminfo.

Expected behavior

User guide correctly reflects what gets installed with GHC

Environment

• GHC version used: 8.6.4
• Operating System: Gentoo Linux
• System Architecture: X64
