* models(gallery): add deepseek-v2-lite

Signed-off-by: Ettore Di Giacinto <mudler@localai.io>

* Update deepseek.yaml

The trailing space here is presumably part of the template string - try use a chomp keep to get yaml lint to accept it?

* Update deepseek.yaml

chomp didn't fix, erase the space and see what happens.
