Bug: Having monaco-editor in package.json causes many similar license files in the build

[itsmylife]

Which package(s) does this bug affect?

• Create Plugin
• Sign Plugin
• Plugin E2E
• Plugin Meta Extractor
• Plugin ESLint Rules

Package versions

v7.6.1 and v7.8.0 and maybe other versions too. But I tested with those two only.

What happened?

In https://github.com/grafana/grafana-prometheus-datasource we have proemtheus datasource and grafana-prometheus npm package which holds prometheus frontend components. When we build the datasource in the dist folder we have a bunch of license.txt files. Considering that we have monaco-editor in the grafana-prometheus package.json having license file is normal. But having 81 of them is not.

What you expected to happen

I'd expect to have only one license file for monaco-editor not as many as the chunks of it.

How to reproduce it (as minimally and precisely as possible)

1. Clone https://github.com/grafana/grafana-prometheus-datasource
2. Install dependencies via yarn install
3. Run 'yarn build'
4. Check the root level dist folder
