What does this PR do?

Upgrades Outlines package in the server to 0.1.1.

Outlines has released a number of fixes and improvements since the current version (0.0.34). Some highlights:
Compatibility with VLLMs
Support min/max number of digits for numbers in JSON Schema
Exclude escape character in JSON string fields (prevents invalid JSON generations)
Allow json ints to be negative

And more. This change should help everyone counting on reliable structured outputs.

Who can review?

@Narsil I noticed you reviewed the last Outlines version bump, so tagging you for review.

@Narsil any thoughts on this? We're using TGI with guidance in production and encountering parsing errors. Upgrading Outlines should fix some of those errors.

If it makes the process easier I can open an issue as well.

Thanks for this PR. Everything looks good, we upgraded other packets as well so the poetry.lock seems outdated now, could you rebase ?

I can take care of it if you want, I'll open a PR for the CI to run, and we'll see if this breaks anything.
