docs(workflows): gate step docstring lists the 'retry' on_reject behaviour (#3656)

The GateStep docstring said on_reject "controls abort / skip behaviour",
omitting the third value. validate() accepts 'abort', 'skip', or 'retry',
and execute() has a dedicated retry branch (returns PAUSED so the next
resume re-runs the gate) distinct from abort (FAILED) and skip (COMPLETED).
Add 'retry' to the docstring so it matches the same file's validate() and
execute() authority.
