docs(node): fix the archive and state sync node settings

node-types.mdx had the two mistakes the nodes skill had. Archive nodes
also need ss-keep-recent = 0, or the SeiDB state store keeps pruning
history. A state sync provider serves snapshots with a non-zero
[state-sync] snapshot-interval in app.toml; [statesync] enable in
config.toml makes a node consume them.

 - RPC / full nodes: these nodes are generally used for querying data or interacting with the chain. They maintain some state but not since genesis. The default settings will run RPC / full nodes.

To enable this type of node, set `min-retain-blocks=0` and `pruning="nothing"` in your `app.toml`, and set `ss-keep-recent = 0` under `[state-store]` so the SeiDB state store keeps every version.
 
-- State Sync Nodes: provide snapshot data for other nodes to use to bootstrap onto the chain. To enable this type of node, set `enable=true` under the `[statesync]` section in config.toml.
+- State Sync Nodes: provide snapshot data for other nodes to use to bootstrap onto the chain. To enable this type of node, set a non-zero `snapshot-interval` under `[state-sync]` in `app.toml`. The `enable=true` setting under `[statesync]` in `config.toml` does the opposite: it makes a node bootstrap from other nodes' snapshots.
 
 - Validator Nodes provide security to the chain by proposing and signing blocks. To enable this type of node, set `mode=validator` in `config.toml`. Note that because Sei is proof-of-stake, you must have enough delegation to join the active set.
