Contributions summary:François-guillaume's commits primarily involve modifying a file (`platform/node/index.js`) containing an array of disposable email domain names and adding new entries. They also added a new file (`platform/node/index.tmpl.js`) that uses a template to generate the index.js file. Furthermore, they modified other files to use the generated index.js file. This suggests a focus on maintaining and extending the disposable email domain list used by the library and making this domain list more easily maintainable through the use of templates.
