fix(adguardhome-sync): deprecated variable update, boolean values (#22694)

**Description**
See deprecation notice here:
[https://github.com/bakito/adguardhome-sync/wiki/Deprecations#deprecation-of-environment-variables-as-of-v060](https://github.com/bakito/adguardhome-sync/wiki/Deprecations#deprecation-of-environment-variables-as-of-v060)

Also change boolean values to bool instead of string, hopefully fixes
this error when running `heavyscript update` on Scale:
```

**⚙️ Type of change**

- [ ] ⚙️ Feature/App addition
- [x] 🪛 Bugfix
- [ ] ⚠️ Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [ ] 🔃 Refactor of current code

**🧪 How Has This Been Tested?**
It has not. If there is a good way for me to test, let me know and I
will.

**📃 Notes:**
Not sure if changing variable names is breaking, will people have to
reinput them? If so close and I can bump minor version instead of patch.
Or if there's a way to direct the chart how to rename current values let
me know and I'll do that.
