By now it should be dry, or close to it. There may be a small amount of moisture still in there though.
If you have some compressed air, try using that first. It probably won't work, but it's easy to try and the least intrusive.
I'm not real familiar with laptop keyboards. With a regular separate keyboard you'd want to pop the keys out. That way you can get in there and clean it good.
Besides the tea, there will also be a lot of other crud that has accumulated over the years. Stuff like hair, food crumbs, dust, and various unidentified stuff that you aren't sure if you want to know what it is.
I'm pretty sure you can do the same thing with a laptop keyboard, but you might want to check with the manufacture or a repair technician first. You can pry the keys off with something like a screw driver. Don't use anything sharp. It's easiest to start with an outside row and work inward.
After the keys are out, clean everything good with paper towels, Q-tips or something similar. You can dip the paper towel or Q-Tip in water if you need to. There is nothing electrical in there, so water won't hurt it. The electrical stuff is very well insulated from the mechanical switches by a thick membrane. If you had sugar in your tea, it might cause stickiness which might require a bit more water. If you use any water, make sure it's completely dry before putting it back together. Compressed air or a fan will help with this.
If you pop the keys off, you might want to take a picture first so you know where all the keys go.
This video shows popping the keys out (about the first 20 seconds). I would not go further taking the small parts apart like the rest of the video unless you are comfortable doing things like that. Hopefully just popping the keys will be enough.
