fix: add 30s sleep to wallet build Docker files

Added a 30-second sleep command to the wallet build Docker files to ensure the container fetches the latest commit before starting the build process. This update guarantees that the build process uses the most recent code, preventing potential issues from delayed and outdated commits.

Changes include:
- Inserted sleep 30s in Docker build scripts.

This enhancement improves build reliability and consistency.
