docs: add IFD FAQ (#246)

* docs: add IFD FAQ

* docs: mirror IFD FAQ to docs

* docs: reword IFD FAQ to those ports

* chore: update IFD list

* chore: remove dunst from IFD list

The IFD from dunst was removed in #302

* docs: FAQ IFD apply suggestions

* docs: FAQ IFD add spotify-player

* docs: cleanup IFD module code example

Seems spotify-player doesn't required IFD either as it's source is from
a builtin
