Fix generation of ./INSTALL for the distribution tarball
"make dist", in charge of creating a distribution tarball, failed when
attempting to generate ./INSTALL as a new reference added to
guc-default-toast-compression on the documentation for the installation
details was not getting translated properly to plain text. Like all the
other link references on this page, this adds a new entry to
standalone-profile.xsl to allow the generation of ./INSTALL to finish
properly.
