fix: use custom fact to write Rosetta app.version to global.properties file...

fix: use custom fact to write Rosetta app.version to global.properties file instead of the hardcoded shit that was used before and broke my installation

files/etc/ansible/facts.d/rosetta_app_version.fact

+#!/usr/bin/env bash
+
+# example string in global.properties file:
+# app.version=8.1.0.0
+if [[ -e "/exlibris/dps/d4_1/system.dir/conf/global.properties" ]]; then
+	ver=$( grep -r "app.version" /exlibris/dps/d4_1/system.dir/conf/global.properties | cut -d "=" -f2 );
+	echo "{\"version\" : \"${ver}\"}";
+fi

+# This custom fact script assumes that whatever app.version is set in the
