chore(deps): upgrade Rollup dependencies

This upgrades Rollup and related dependencies. Note that some of the plugins are now published under the @rollup NPM scope.

• rollup@1.16.2 -> rollup@1.28.0 (changelog)
• rollup-plugin-commonjs@10.0.1 -> @rollup/plugin-commonjs@11.0.1 (changelog)
• rollup-plugin-node-resolve@5.1.0 -> @rollup/plugin-node-resolve@6.1.0 (changelog)
• rollup-plugin-replace@2.2.0 -> @rollup/plugin-replace@2.3.0 (changelog)
• rollup-plugin-vue: 5.0.1 -> 5.1.4 (changelog)

Some of these packages have now dropped support for Node versions prior to v8, which isn't a problem for us since we already require Node 8: https://gitlab.com/gitlab-org/gitlab-ui#prerequisites

To make sure that nothing will break in GitLab because of these upgrades, here's an integration MR: gitlab!22488 (closed)
