fix: solid-start merge babel options

[lxsmnsyc]

Probably an oversight. solid-start's vite plugin completely omits the babel option for vite-plugin-solid.

As for the server transform, I'm not sure where to put it, but for now I'll just use push.

We also have another section where we use the solid babel compiler and override it with options:

    async transform(code, id, transformOptions) {
      const isSsr =
        transformOptions === null || transformOptions === void 0 ? void 0 : transformOptions.ssr;
      let babelSolidCompiler = (code, id, fn) => {
        // @ts-ignore
        return solid({
          ...(options ?? {}),
          babel: fn
        }).transform(code, id, transformOptions);
      };

Could you see if we could do something about this as well?

Also, thanks for helping with this!

@nksaraf which part is this?

This is the transform function from function solidStartFileSystemRouter(options)

Okay so I've fixed it, not sure with the conflicts
