The bug
The spawner is completely absent from the Creative inventory for some reason. It would be expected it would be there, as it isn't a very technical block like barriers or command blocks which have been intentionally kept out of the Creative inventory.
This is also a parity issue, as the spawner does appear in Bedrock Edition's creative inventory. The fact that it exists in the Creative inventory in Bedrock Edition may be due to some behavioural differences; placed spawners are empty by default in Bedrock Edition, but spawn pigs in Java Edition, so it may be advisable to make Java Edition's behaviour match Bedrock Edition's.
How to reproduce
Give yourself a spawner: /give @p minecraft:spawner

I wonder if this as something to do with Java not having just an empty spawner block. It's default is pigs. This is unlike Bedrock, which can just be empty. This is a parity issue itself, but I wonder if maybe because it can't really be used for decoration like Bedrock, it just isn't in the inventory.
(also, I'd be surprised if this report stays open. any parity issue from pre 1.14 times seems to count as a "suggestion", not "bug".
