[jesuino]

A PR for RHIDP-2110 and RHIDP-2123.

Related PR: janus-idp/backstage-showcase#1285

After manually testing and checking the command then I used the following script to update all package.json( it requires jq to run).

#!/bin/bash
for plugin in ./plugins/*
do
        package="$plugin/package.json"
        echo "Opening $package"
        echo $(
                cat "$package" | jq -r '
                                if  .scripts."export-dynamic"  then
                                     if .backstage.role == "frontend-plugin" then 
                                             .scripts."export-dynamic" += " --in-place"
                                     elif (.backstage.role == "backend-plugin-module" or .backstage.role == "backend-plugin") then
                                             .scripts."export-dynamic" += " --no-embed-as-dependencies"
                                     else
                                             .scripts."export-dynamic" = .scripts."export-dynamic"
                                     end
                                 else .
                                 end
                                ') > $package
