feat: take ownership on pipeline schedule variables
requested to merge zadkiel_aharonian_c4/terraform-provider-gitlab:zadkiel_aharonian_c4-main-patch-41340 into main
Followup !1745 (merged) Relates to #1400 (closed)
If some pipeline schedule variable is edited (without the associated pipeline schedule being modified), the API may return an error if the applying user is not the current owner of the pipeline schedule. Adding this option will help circumvent this by taking ownership before creating/editing/deleting the variable.
