feat: Add support for Node 22

[ceciliaavila]

#minor

Description

This PR adds support for Node 22 by fixing issues with the import-sync package and the deprecated method crypto.createDecipher.
It also updates the yaml files to include Node 22 in the testing matrix and to use this version to run the GitHub actions.

Specific Changes

• Removed incompatible import-sync package and used tsup to compile the ESM-only dependency, filenamify.
• Added a condition to return a descriptive error message if the legacyDecipher method is used under Node 22, because crypto.Decipher was removed.
• Fixed unit tests in loadAndSave.tests.js to include the new error message.
• Updated all yaml files from GitHub actions and CI pipeline to include Node 22.
• Added the NODE_NO_WARNINGS flag in schemaMergeTest.js to avoid the execution of bf dialogs:merge to fail due to a deprecation warning.

Testing
