INSTALL.md — reorganise info on static binaries and add conda-forge install options (#10098)

See #10069 -- the static linked pandoc on other OSes also
have a limitation to use binary lua packages. So added
this point at the top of the document. In addition
conda-forge is cross-platform way to install pandoc
and other tools, added to Windows, macOS and
Linux sections.
