Increase MAX_ENTRIES limit in ZipBombChecker to support larger test packages

[abhishekbedi1432]

Description

Increased MAX_ENTRIES limit from 10,000 to 20,000 in ZipBombChecker.java to support uploading larger test packages with more files.

Problem: Test packages (e.g., iOS XCTest bundles) can contain more than 10,000 files, causing the zip bomb detection to incorrectly reject legitimate uploads.

Solution: Increased the MAX_ENTRIES constant to 20,000 to accommodate larger packages while still protecting against zip bomb attacks.
