Alternatively, use the machine-readable JSON output from "postqueue -j":
$ postqueue -j | jq -r '
first(select(.queue_name == "deferred" and
(.queue_id | test("^[0-9A-F]+$")) and
(.recipients[].address | test("^.ostmaster"))))
| .queue_id
'

I have a "deferred" message addressed to "postmaster" and "hostmaster"
at a poorly operated domain, so the "queue_name" was "deferred". In
your case it should be "hold".
To avoid trusting the low-privilege Postfix user to supply arguments
for commands run as root, the queue id is filtered to be of the
expected upper-case hexadecimal form.
Because the recipient test (deliberately, to make the point) matches
either recipient, to avoid reporting the same queue file multiple times
,once for each matching recipient, the select(...) is pruned to the
first match via first(select(...)).

Release all quarantined mail from "harml...@example.net" to
"artl...@example.org" (and any other recipients of the same message
envelope):
# jq -r '
first(select(.queue_name == "hold" and
(.queue_id | test("^[0-9A-F]+$")) and
.sender == "harml...@example.net" and
(.recipients[].address == "artl...@example.org")))
| .queue_id
' | postsuper -H hold
