Since 1.54.1 the package bundling is no longer "deterministic", that means we are re-deploying packages with no code changes.

Describe the bug
The commit in version 1.54.1 introduced a bug in the bundling process. The produced zip files are always binary different, with no code changes involved.

The consequence is that the packages are being re-deployed every time, as if they contain changes.

To Reproduce
In any repository, run:

# create a package
npx sls package
# save the zip file
mv .serverless/*.zip first.zip
# repeat package creation
npx sls package
# save the second zip file
mv .serverless/*.zip second.zip
# Now compare them
diff first.zip second.zip
# diff will tell the "binary files differ".

The cause is the modification date. You can unzip -l first.zip and unzip -l second.zip to see.

Expected behavior
The zip files should be bundled in a "deterministic" way, that means, bundling the same code should always produce the exact same bundle.

Additional context
If you downgrade to version 1.53.0, the plugin works in the expected way.
