* Update docs for --configPlugin using typescript

The documentation gives examples for using `@rollup/plugin-typescript` to parse the Rollup configuration file, with a CLI code example. However, that example will fail to build with a somewhat misleading error if the Rollup config is not declared in the `tsconfig.json`'s `include` property, so a note about needing to do so has been added with this commit.
