Getting error when update Node.js is attempted
### Analysis

I have Homebridge running on DSM 7 

I'm trying to update Node.js as when I go to update plugins, it complains that I should be at newer version (v16.19.1) than where I am (v16.16.0).  

This is interesting as the Synology itself is running 18.12.0-0005.
Node.js was updated via Synology update process for other apps to version.

I see that 16.x should work fine for now, that 18.x is supported as well....
Node.js 16.x until September 2023
Node.js 18.x until April 2025

However, when I go to update Node.js, I get an error:
homebridge@indy:/volume1/homebridge $ hb-service update-node 
ℹ Updating Node.js from v16.16.0 to v18.15.0...
✖ Cannot update Node.js on your system. Synology DSM 7 does not currently support Node.js 18 or later.

This perhaps is just an issue with Synology and versioning, but since Synology did the update to get Node.js to 18, it seems odd that the output is saying it is unsupported.



### Expected Behavior

I'd expect that Homebridge would see / notice that Node.js had been updated to 18.12.  

Other than that, I wouldn't expect an unsupported error when I attempt to do the update to get Homebridge to see the update.  

### Steps To Reproduce

I ssh to Synology
sudo to root
issue hb-service update-node 

also tried:
hb-service update-node 18.12
(same error)
