fastify support

[rodrigo1991]

Please change
res.json({ success: true, code: code });

to
res.send({ success: true, code: code });

to make it work on both express and fastify router

I have encountered this error:

TypeError: res.json is not a function
    at /app_path/node_modules/passport-magic-login/src/index.ts:105:13
    at processTicksAndRejections (node:internal/process/task_queues:95:5)
TypeError: res.json is not a function
    at /app_path/node_modules/passport-magic-login/src/index.ts:109:13
    at processTicksAndRejections (node:internal/process/task_queues:95:5)

It occurs right after sending the email with the MagicLink to the user.
I'm not sure if it could be related to this Issue since I'm also using Fastify (with NestJs).

EDIT: Using NestJs through Express, I don't get the above-mentioned error, so I understand that this is the reason for the failure.

Example workaround for unpatient people.

@Post('login')
loginWithLink(@Req() req, @Res() res) {
  this.passwordlessStrategy.send(req, {
    ...res,
    status: (code) => {
      res.statusCode = code;
      return res;
    },
    json: res.send.bind(res),
  });
}

The underlying project is based on Nest.js, but hopefully you get the idea. Patch json() and status()
