Update Bootstrap 5.2.x to 5.3.x

Hello everybody,

I want to update my bootstrap version in yii2/bower-asset.

There is a composer.json file in the vendor/bower-asset/bootstrap folder. So I think I can update the asset separately with composer update. But I have come to the conclusion that there is nothing to update. At the moment boostrap v5.2.1 is installed. The latest stable version is v5.2.3. But the composer does not find them.

When I run composer update twbs/bootstrap i became the error message:

Cannot update only a partial set of packages without a lock file present. Run 'composer update' to generate a lock file.

I’m no pro with Composer. Maybe someone has a tip for me which parameters I can use.
