install: Drop single-node-developer profile

There's an enhancement proposal for this profile [1], and the Code
Ready Containers folks took a run at using it in [2] before backing
off in [3].  I don't have any problems with having a specific CRC
profile, but if we end up going that way, we'll need a lot more CVO
manifests with the annotation than just these two admin-ack ConfigMaps
(e.g. we'll probably also want the CVO's Namespace and Deployment,
etc., or there won't be anything consuming the admin-ack ConfigMaps
;).  This commit drops these two annotations, which slipped in when
the ConfigMaps landed in 519b466 (Bug 1978376: Add admin ack
Upgradeable condition gate, 2021-07-27, #633).
