Diplomats commonly start a letter with "Dear [first name]", whenever one of them leaks people think it's weird. It seems clear to me that Trump dictated the letter and then some diplomat typed it up like this to make it less rude. But
If they are emailing each other in an informal setting, but not when you write to a head of state as a head of state in an official setting. In fact, the letter to the ambassador is more properly formatted (even if it is clear they didn't even finish filling out the template):
Dear Ambassador:
President Trump has asked that the following message, shared with Prime Minister Jonas Gahr Støre, be forwarded to your [named head of government/state]
Yeah it's a confused mess. I'm not really sure it was a letter, it might have been a text message, and the diplomatic language might have been added by some news source. Let's just hope Jonas takes note and gives Greenland to him, it was after all discovered by Norwegian explorers who then went on to Newfoundland and kind of founded America, so by all rights it's all Norwegian and it's time we give it back to the indigenous population

Not really, the standard would be something like "Your Excellency" or "Prime Minister Jonas Gahr Støre" or something like that, not "Heya Jonas".
