Remnant default pref in "2019 preview" builds

[Vangelis66]

In the 1.7.8.2019.xx.xx builds of CTR, targeting mainly (Classic) Waterfox 56 and official Basilisk 52,

removed the option "add-on manager version number"
Basilisk 2019 and Waterfox don't need this option, because version number is active by default

However, the corresponding (default) pref has been left behind:

ClassicThemeRestorer/xpi/defaults/preferences/options.js

Line 91 in a3c2575

pref("extensions.classicthemerestorer.addonversion",true);

but, instead, with a value of false ; the value itself (true | false) is irrelevant here, as the GUI option has been removed from CTR (as per release notes); shouldn't the same apply to the pref itself?

Unless, OTOH, this is still needed to support Firefox v52-56; in any case, it shouldn't apply to Basilisk (because it is present inside Basilisk's about:config tab), should it? ...

Apologies in advance if I have figured things the wrong way...
Best regards 😄

You are right, the pref can be removed as it does not even get monitored but CTRs observers anymore. It does no harm though.
