support `jsxImportSource` option about rollup-plugin-esbuild

@anuoua I thought the same thing because this isn't listed in the plugin's docs, but it appears to be working just fine when used.

Providing jsxImportSource in the plugin configuration does seem to work. However, I would argue that this property should also default this property from the tsconfig.json as described below for the other options:

It uses jsx, jsxDev, jsxFactory, jsxFragmentFactory and target options from your tsconfig.json as default values.

To do so, we'd need to add jsxImportSource in the destructure here.

--    const { jsxFactory, jsxFragmentFactory, target, jsx } =
++    const { jsxFactory, jsxFragmentFactory, target, jsx, jsxImportSource } =
      data.compilerOptions || {}
