Use bundler gem tasks instead of gem_release

Now that we also have a solidus_admin that follows a different release
track we need more control over what gems are released. `gem_release`
has no such control available and simply has a configuration for
recursing. Also all the features of `gem_relerase` regarding version
numbers manipulation are no longer relevant as it all happens within
GitHub actions using dev_tools.

Bundler gem tasks are now the standard for all our extensions and are
a simpler, already available, tool that can be leveraged here as well.
