JS files in public folder evaluated after copy and upload

[traffisco]

Describe the problem:

Files with JS extension in the public folder are evaluated on yarn deploy.
The folder intended for static files to be uploaded and scripts shouldn't be evaluated.

Link to a minimal reproduction:

https://github.com/traffisco/yarn-bug-test

Added new file test.js with "error" typed in it.

yarn deploy fails with error:
"message": "Uncaught ReferenceError: error is not defined\n at line 22\n"

Files do get copied to out folder and uploaded to KV. Instant workaround is to delete the files from the public folder.

Looks like wrangler publish have a bug with webpack CopyPlugin

flareact/configs/webpack.worker.config.js

Line 32 in 0d0a836

new CopyPlugin([

Quick fix is to move file copy from webpack to another place like

flareact/src/bin/flareact.js

Line 93 in 0d0a836

if (argv._.includes("publish")) {

I can make a PR if you interested
