feat: add flag to geolocation

[PaulieScanlon]

This PR adds flag to the geolocation export in the edge package.

E.g

import { geolocation } from '@vercel/edge';

export default async function handler(req) {
  const { flag } = geolocation(req);

  console.log(flag)
}

export const config = {
  runtime: 'edge',
};

I've branched this PR and running the tests here: #10496

[cb1kenobi]

Code looks good, manually tested and works great. However, I branched this PR to run the tests (#10496) and the "docs are up to date" test is failing: https://github.com/vercel/vercel/actions/runs/6164248432/job/16729621798?pr=10496. I can also cause the tests to fail when running pnpm test-unit from the packages/edge directory. Give this a look and I can re-run the tests.

Hi @cb1kenobi, thanks for looking at this, with regard to failing tests. I've just pulled this branch and the following tests are failing, they are all outside of the edge package.

• test/utils/changelog/parse.test.js
• test/utils/changelog/filter.test.js
• test/utils/changelog/group.test.js

I don't believe any of the changes I've made touch these tests, could it be they are failing from a previous commit?

I have update the docs by running pnpm build:docs... is that what I needed to do? sorry, totally confused by this repo!

[PaulieScanlon]

When i run pnpm test from the edge package, it changes all the references to the line numbers to use my username.

All the tests in the edge package now pass but what am I doing wrong? Why does running tests change stuff in a .md file?

[cb1kenobi]

@PaulieScanlon I honestly don't know why it's changing the URLs. We don't have to deal with that because we don't use forks. In any case, I just pulled your branch into my PR so the tests can run. Fingers crossed! :) #10496

[cb1kenobi]

@PaulieScanlon Tests pass! #10496

Huge thanks!

[PaulieScanlon]

@cb1kenobi Super stuff! Do you know when this will likely be published to npm?

[cb1kenobi]

@PaulieScanlon should be soon, like, this week. Hopefully. :)
