Add script for updating composer dependencies

This commit includes a new file, updates.sh, which is a script that updates the composer.json file and its dependencies to their latest versions. It ensures that not only the dependencies explicitly listed in the composer.json file are updated, but also all of their dependencies. Furthermore, if any command fails, the script will stop immediately.

+# This script updates the composer.json file and stops on error.
+# It first updates the composer dependencies to their latest versions that still satisfy the version constraints in the composer.json file.
+# Then it upgrades the composer dependencies to their latest versions, ignoring the version constraints in the composer.json file.
+# Finally, it bumps the version of the composer package.
+# The -W (or --with-all-dependencies) option tells Composer to update not only the dependencies explicitly listed in the composer.json file, but also all of their dependencies.
+# If any command fails, the script stops immediately.
