Support stable release of `transformers` in `requirements.txt`

[songyuc]

Hi LLaVA-NeXT team,

I noticed that the current requirements.txt specifies:

transformers==4.40.0.dev0

This is a development version. I would like to suggest supporting a stable release of transformers (e.g., transformers==4.45) for the following reasons:

1. Stability: Stable releases are thoroughly tested and less likely to introduce breaking changes.
2. Compatibility: Using stable versions improves compatibility across different user environments.
3. Ease of installation: Users can install stable releases directly via pip without relying on dev channels.
4. Community support: Issues encountered with stable releases are easier to find solutions for, compared with dev versions.

If needed, automated tests or CI can be used to ensure compatibility with the newer stable releases.

Thank you for considering this suggestion. Your work on LLaVA-NeXT is amazing, and supporting stable dependencies would make it even easier for the community to adopt and reproduce results.

Best regards,
Yucheng Song
