fix: Make quiet_archive_local_exec properly suppress Poetry/pip/npm output

[ruhrohraggy]

Description:

The quiet_archive_local_exec variable was not being honored by the actual packaging subprocess calls in package.py. This change passes the
quiet flag from Terraform to the Python script and suppresses all packaging output when enabled.

Problem:

• quiet_archive_local_exec only suppressed Terraform's local-exec output, not the actual packaging commands
• Poetry, pip, npm, and zip subprocess calls were still producing verbose output during builds
• Users experienced noisy Terraform output during Lambda packaging operations

Solution:

• Pass quiet flag from Terraform → package.py → build plan → subprocess execution
• Suppress stdout/stderr in Poetry, pip, and npm check_call() when quiet=true
• Suppress zip creation and file logging in ZipWriteStream when quiet=true
• Suppress completion messages when quiet=true

Changes Made:

1. package.tf: Pass quiet_archive_local_exec to external data source and local-exec
2. package.py:
   • Add quiet to build plan data in prepare_command
   • Suppress Poetry/pip/npm subprocess output when query.quiet is true
   • Add quiet parameter to ZipWriteStream class
   • Suppress zip logging and completion messages when quiet mode enabled
3. examples/build-package: Add demonstration of quiet packaging functionality
4. Documentation: Update README to explain quiet packaging feature

Testing:

• [x] Added package_dir_poetry_quiet example demonstrating quiet_archive_local_exec = true
• [x] Verified Poetry, pip, npm, and zip output is suppressed in quiet mode
• [x] Confirmed backward compatibility - no output change when quiet_archive_local_exec = false
• [x] All pre-commit hooks pass successfully

Breaking Changes:

None. This is a backward-compatible bug fix.

Resolves:

• fixes #706 - quiet_archive_local_exec not working for Poetry/pip/npm output
• Provides truly quiet Lambda packaging builds for cleaner Terraform output

@antonbabenko just tagging for visibility! Appreciate any time you have to review

Hey @ruhrohraggy - thanks for working on this! I've been testing out your PR and found that it's missing a variable declaration for quiet_archive_local_exec. Other than that it seemed to work well.

@hristost-pearl quiet_archive_local_exec is there already - https://github.com/terraform-aws-modules/terraform-aws-lambda/blob/master/variables.tf#L807-L811 ... or not?

Should be... Like #706 pointed out, it was just that the variable didn't seem to be getting applied as expected.
