pnpm run swallows empty strings given as parameters

[deiga]

pnpm version: 8.5.1

pnpm swallows empty strings from cli arguments, which breaks scripts that might have those

Code to reproduce the issue:

1. Add a echo script to package.json => "echo":"echo",
2. run the script pnpm echo "foo" "" "bar"

Expected behavior:

• > echo "foo" "" "bar"
• foo bar

Actual behavior:

• > echo "foo" "bar"
• foo bar

Additional information:

• node -v prints: v16.16.0
• Windows, macOS, or Linux?: maOS

It seems to be caused here, not sure if this should be fixed, maybe we can just filter the empty string in params for install command.
