fix(admin-ui): modify webpack config to prevent throwing sourcemap errors

[kasperkristensen]

What

• A error started popping up in our CI, and has been reported by users in our Discord, that the admin would fail to build. The error seemed to stem from ´source-map-loader´ failing to process prism-react-renderer.
• This PR removes the loader, this may cause browsers to not be able to interpret source maps from some third party libraries.

LGTM!

this may cause browsers to not be able to interpret source maps from some third party libraries.

Do you think we should include this in the release notes as a breaking change?

[kasperkristensen]

@olivermrbl Not a breaking change, but might be worth to include a note, as it makes it harder to debug third party dependencies. Needing to debug npm packages should be an edge case, but sometimes necessary and in that case this makes that process harder, as you will be left with debugging the compiled code.
