Keep attachments on tasklist update (go-gitea#16750) (go-gitea#16757)

* Send attachments too.

* Use tasklist flag.

* use action="ignoreAttachments" instead of "tasklist"

* Use boolean parameter.

* when the update request doesn't intend to update attachments (eg: change checkbox state), ignore attachment updates (go-gitea#16762)
