Upgrade node12.x to v12.18.2 to support ES Modules without a flag

[alekseykulikov]

AWS recently upgraded node12.x to v12.18.2. It means it supports ES Modules without a flag 🎉

ES Modules support starts since v12.17.x, and Lambci is v12.16.3, which matches the previous version of node12.x.

AWS Lambda version:

exports.handler = async (event) => {
    return process.version; // v12.18.2
};

Lambci version:

$ docker run --rm --entrypoint node lambci/lambda:nodejs12.x -v
v12.16.3

You're right, but this update is in the process of being rolled out – it hasn't rolled out to all regions yet (for example, it hasn't rolled out to ap-southeast-2 yet).

It should be finished in the next few days, but there's a chance it will be rolled back too, if issues are encountered in other regions.

I'll let you know when it's finalized and I've pushed up updated images

Took a while, but it finally rolled out to all regions this morning! I've since updated the images 👍
