Migrate copy-webpack-plugin to tinyglobby

[benmccann]

It has been agreed to by the maintainers: webpack-contrib/copy-webpack-plugin#788

I already had a PR merged to simplify the glob usage in the project, which should make it a bit easier: webpack-contrib/copy-webpack-plugin#789

I'd love for someone to take this over the finish line!

I'd looked briefly at doing it and had trouble with their spell checking thinking that tinyglobby isn't a word (while being okay with fast-glob and globby). I wasn't able to configure their spell checker for whatever reason (maybe I missed some step or something), but I did get tinyglobby added to the base dictionary: streetsidesoftware/cspell-dicts#3756. So when there's a new release of that it should help make things easier (i.e. wait for streetsidesoftware/cspell-dicts#3751 to be merged)

copy-webpack-plugin has been updated to the latest version of cspell. Hopefully the migration should be unblocked now.
