I'm sure you understand why. Ukraine is in a vulnerable position right now and needs all the allies it can get. Alienating Turkey would be foolish. And considering the Armenian genocide happened a long time ago, it's not exactly worth it to bring this up now. Turkey, especially under Erdogan, is definitely a problematic country, but not one that either Ukraine or NATO can afford to alienate right now. Current issues take precedence over the atrocities of the past.
