v3.13.0

• Adds serviceAccount option to runtimeOptions to specify which service account Cloud Function should use at runtime. For example:

const functions = require('firebase-functions');

exports.myFunction = functions.runWith({
    serviceAccount: 'test-sa@project.iam.gserviceaccount.com'
    // OR
    // serviceAcount: 'test-sa@"
    // OR
    // serviceAccount: 'default'
  })

Requires firebase-tools@8.18.0 or later. Thanks @egor-miasnikov!

• Upgrades highlight.js to 10.4.1 to fix a vulnerability.
