Remove unused store module in Dependency List

What does this MR do?

Remove unused store module

As part of Update dependencies table UI, the Dependency List is being reduced from two tabbed lists to just one.

That work is taking place behind the dependency_list_ui feature flag. When it's disabled, the old UI will be rendered, which means the store needs to be created with list modules for both the "All" and "Vulnerable components" tabs.

When the flag is enabled, only the default "All" list module needs to be set up. Otherwise, the UI would make an initial unnecessary network request for the "Vulnerable components" tab/list, which isn't being rendered.

#212867 (closed) will address the clean up after the dependency_list_ui feature flag is removed.
