Fix/pnpm install crash

[Vivian-04]

Description

This pull request resolves a critical installation failure occurring in CI/CD environments using pnpm@10.33.0. The crash was caused by a known bug in pnpm where it attempts to process non-directory files (like .gitkeep) as workspace packages if they match defined globs in pnpm-workspace.yaml.

Removing these redundant .gitkeep files stabilizes the dependency resolution process and ensures that the build pipeline can proceed without manual intervention or pnpm version downgrades.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

• Verified that .gitkeep files were matching the workspace globs.
• Confirmed that the error Cannot use 'in' operator to search for 'directory' in undefined is a documented bug in pnpm@10.33.0 triggered by files matching globs.
• Verified local deletion of the files.

Test Configuration:

• Firmware version: N/A
• Hardware: N/A
• SDK: pnpm 10.33.0
