Synology homebridge install fails due to Node.js v20 prereq
### Analysis

Used the steps provided in the Synology/Homebridge install doc to install Homebridge.

The install fails because it requires Node.js v20 (the doc refs the Node.js v18 prereq). v20 isn’t available on DSM yet


### Expected Behavior

According to the install doc Node.js v18 should be the prerequisite not v20

### Steps To Reproduce

1. Configure DSM to include the Homebridge Synology package home
2. Search for Homebridge in the DSM package manager
3. Click the install
4. Error dialog will pop up asking for Node.js v20 to be installed
