homebridge-config-ui-x 4.76.0 on Node.js NPM

A new version of Homebridge UI (v5) will be released around mid-June 2025. This will be compatible with both Homebridge v1 and v2 (in beta).
Initially, there will be no significant differences between Homebridge UI v4 and v5. The major version increment primarily reflects the removal of support for outdated technologies and hardware. UI v5 will:
- Be compatible with Homebridge v1 and v2
- Drop support for Node.js v18 and earlier, so please update to v20 or v22 - more info on updating
- Drop support for Raspberry Pi devices running on the armv6 architecture (like the Pi 1 and Pi Zero) - please update your hardware
- Drop support for instances using pnpm as the package manager - consider updating your Homebridge instance to use npm instead - more info on updating
Note that these are not requirements for UI v4.76.0
