Install neo4j with zip files in macos instead of brew.

[mwqgithub]

Purpose of the change

Support configuration script in older macos systems. Avoid installing xcode

Description

In older macos systems like macos-12, homebrew doesn't provide pre-compiled jdk and jdk has to be compiled locally when installing neo4j. This makes the installation of neo4j depends on Xcode, which is very large.
So we would like to switch to download the pre-built java binary and neo4j binary directly and extract them. Like we do in linux and windows.

Pull request overview

This PR modifies the macOS installation process to use pre-built binaries downloaded directly via zip/tar files instead of relying on Homebrew, eliminating the dependency on Xcode in older macOS systems like macOS-12.

Key changes:

• Replaces Homebrew-based Neo4j installation with direct binary downloads for macOS
• Adds support for both ARM64 and x86_64 architectures on macOS
• Updates test infrastructure to verify installation on both macOS architectures

The Neo4j version is hardcoded here but defined as NEO4J_DIR_NAME in utilities.py. Use NEO4J_DIR_NAME instead to maintain consistency and avoid duplication. This should be: neo4j_dir = str(Path(self.install_dir) / NEO4J_DIR_NAME)

Suggested change

	neo4j_dir = str(Path(self.install_dir) / "neo4j-community-2025.09.0")
	neo4j_dir = str(Path(self.install_dir) / NEO4J_DIR_NAME)

The parameter name 'zip_path' is misleading since this method extracts tar files, not zip files. Rename it to 'tar_path' to accurately reflect the file type being processed.

Suggested change

	def extract_tar(self, zip_path: str, extract_to: str) -> None:
	self.extracted_files[zip_path] = extract_to
	def extract_tar(self, tar_path: str, extract_to: str) -> None:
	self.extracted_files[tar_path] = extract_to

The conditional expression uses Python syntax ('or') instead of GitHub Actions YAML syntax. This should use '||' for proper workflow evaluation: if: matrix.os == 'macos-latest' || matrix.os == 'macos-15-intel'

@mwqgithub You may need to check if those copilot comments make sense.

Yes, I think these comments are very useful. Let me fix them.
