Object.fromEntries is not defined in Node.js versions < 12

[hannesj]

In 7e78a23 usage of Object.fromEntries was added to apollo-server-lambda. Package.json specifies that Node.js versions from 6 up are supported. When running apollo-server-lambda in Node.js versions older than 12, I get the error Object.fromEntries is not a function, as support was only added in that version.

This is resolved in the most recent publish: 4fdf6f2

- apollo-server-lambda@2.6.2

Thanks for reporting!
