discourse: Fix icu library mismatch in mini_racer

Browse Source 
After #525241 ("nodejs: pin icu to newer version"), building discourse
assets would fail with a library loading error:

LoadError: /nix/store/3sv7vxglmc6zwg68ycl9xpny87mm6fp7-discourse-ruby-env-2026.1.4/lib/ruby/gems/3.3.0/extensions/x86_64-linux/3.3.0/mini_racer-0.19.1/mini_racer_extension.so: undefined symbol: _ZN6icu_788ByteSink15GetAppendBufferEiiPciPi (LoadError)

This error apparently occurs when the ICU version used by libv8 does not
match the ICU version mini_racer is built with.

Thanks to @0xB10C for identifying the problematic commit.

Fixes #538128
