Unlink assets from a campaign or ad group

Removes the link between an asset and a campaign, ad group or the account, so the extension stops serving there. The asset itself stays in the account library and can be linked again later. Use when: the user has confirmed which extensions should stop showing, by name. Do not use when: the user said "pause" or "turn off for now" and you have not explained that Google has no pause for asset links — removing and re-linking is the only path, and the link's history is lost. Requires confirm_delete: true. Pass the link resource names from google_list_assets (each asset's links[].link_resource_name), not asset ids: an asset id alone does not say which of its links you mean, and an asset with an empty links list is not linked anywhere, so there is nothing to remove. Removing a link is immediate. Nothing else about the campaign changes. If you are unsure which account, campaign or period the user means, ask them — do not guess ids or dates.
