Update requirements_llamaindex.txt

Need to set the version of llama-index-core as 0.10.23.post1, otherwise 0.10.68.post1 would be installed, which will cause the issue ImportError: llama-index-readers-file package not found. (The root cause: in the version 0.10.68.post1, there is an unresolvable import of llama_index.readers.file.PandasExcelReader in llama_index/core/readers/file/base.py)

@abaranovskis-redsamurai might you help to check your local version for llama-index-core? That version might be better. Before the change:
