xlsx number and formula parsing issue

- **Package Name**: azure-ai-documentintelligence
- **Package Version**: 1.0.0b4
- **Operating System**: Windows
- **Python Version**: Python 3.11.0

**Describe the bug**
When parsing a .xlsx file with begin_analyze_document() function and the prebuilt-layout model, numbers smaller than 10 are not parsed. However, decimal numbers smaller than 10 are parsed. Cells containing values that comes from excel formulas are not parsed either.

**To Reproduce**
Steps to reproduce the behavior:
1. Create a .xlsx file with numbers smaller than 10 and a cell containing a formula
2. Parse the file
3. check parsing output

**Expected behavior**
Numbers smaller than 10 and formula cells should be parsed. The parsed output should be as follow:

"page_content\":\"# Sheet1\\ntest\\nint < 10\\n1\\n2\\n3\\n4\\n5\\n6\\n7\\n8\\n9\\nfloat\\n1.5\\nint >= 10\\n10\\n11\\n12\\n13\\n14\\n15\\nsum\\n121.5\\n\"

**Screenshots**
excel sheet:

parsed output:
"page_content\":\"# Sheet1\\ntest\\nint < 10\\nfloat\\n1.5\\nint >= 10\\n10\\n11\\n12\\n13\\n14\\n15\\nsum\\n\"
