[Feature][dbgpt-ext] Update spacy dependency to support Python 3.13 #3006

Search before asking

• I had searched in the issues and found no similar feature requirement.

Description

Currently, dbgpt-ext (specifically for rag and storage-chromadb extras) has a hard-coded dependency on spacy==3.7.

This creates a compatibility bottleneck because spacy 3.7 was released before Python 3.13 and its distributed wheels do not support the Python 3.13 runtime. Users attempting to install DB-GPT on Python 3.13 environments encounter resolution errors or build failures due to missing compatible binaries and deprecated C-API calls in older spacy versions.
