Remove buildScripts/webpack/entrypoints/App.mjs

The only reason this override-file exists was Firefox parsing dynamic imports at build-time instead of run time.

            if (!Neo.config.isExperimental) {
                Neo.onStart();

                if (Neo.config.hash) {
                    HashHistory.push(Neo.config.hash, Neo.config.hashString);
                }
            } else {
                // todo: in case FF still does not support dynamic imports, remove the dynamic import call for FF dev builds

                import(
                    /* webpackIgnore: true */
                    '../../' + me.data.path).then((module) => {
                        Neo.onStart();

                        if (Neo.config.hash) {
                            HashHistory.push(Neo.config.hash, Neo.config.hashString);
                        }
                    }
                );
            }

=> this import() broke the dist versions, although the code was not reachable.

Luckily, this is no longer the case, so we can remove the file now and adjust the entrypoints.
