FIFY.
It was called that as a misnomer due to Soviet/Russian actions to belittle the people there. It's all part of the ethnocentrist propaganda pumping out of there now. Leaders of Russia calling Ukrainians a subethnic group (re, not worthy of having a state). Therefore, when you use "the" Ukraine, you are diminishing who they are, and what they have. I know plenty that are Ukrainians that will fight you tooth and nail about using that article "the."
My family's time over there predates the Soviet Union. I think they moved there in the 1700's to farm or something. They never assimilated. I don't know that any even learned the local languages. Heavy population of those people moved here.
If someone from over there wants to fight about it including "the" before Ukraine, I'll give them directions to a cemetery in the middle of nowhere even by North Dakota standards. They can complain to long dead people.
FWIW, they have nothing. They are dirt poor and grow wheat. That's honorable and all that. But this isn't some capital of culture. No one wants to go there unless they wanna see Chernobyl/Pripyat.
No one is dismished by placing "the" in front of the name of a place and it's silly pretending otherwise. You gonna get mad that I got some frozen Chicken Kiev sitting in the freezer or insist I call it Chicken Kyiv?
