withNx should support custom transform react runtime

[mola-molaa]

when @nx/rollup withNx function set compiler as 'swc', then
package's .swcrc set transform react runtime as 'classic',
tsconfig.json set jsx: "preserve"

after build, index.esm.js in dist still has import {jsx } from 'react/jsx-runime' however the react version is 16;

I found that withNx, when compiler is set 'swc', swc plugin is hardcode ”runtime: automatic“
https://github.com/nrwl/nx/blob/master/packages/rollup/src/plugins/swc.ts
https://github.com/nrwl/nx/blob/master/packages/rollup/src/plugins/with-nx/with-nx.ts#L307

hope withNx function makes developer able custom the runtime option or should the swc plugin respect to package .swcrc
