feat(GlToast): add suport for link actions
What does this MR do?
This adds the ability to provide a link as a toast's action.
This is done to fix an issue where a GitLab toast used to include a link in its message. This was supported by vue-toasted
but isn't with BootstrapVue toasts as the HTML is escaped. We have agreed to move the link to the toast's action instead.
