fix: Exclude litellm==1.107.0 from extras (#8104)

### Description
That version [is
vulnerable](https://safedep.io/litellm-pypi-compromise-credential-stealer-backdoor/#payload-2-the-backdoor-in-sitecustomizepy)
so it would be great to exclude it from extras. To be honest, we don't
use that extra but since we use poetry, the litellm version range shows
up in our poetry.lock and it doesn't look good for our security team.
Thanks!
