Using getStore outside a function only works in dev, not in production

[rhtenhove]

Describe the bug

When using for example:

const blobStore = getStore("foo");

Outside a function, netlify dev is fine with it and will store and retrieve stuff as expected. However when using this in production (or a deploy preview), the following error is thrown.

{
  "errorType": "MissingBlobsEnvironmentError",
  "errorMessage": "The environment has not been configured to use Netlify Blobs. To use it manually, supply the following properties when creating a store: siteID, token",
  "trace": [
    "MissingBlobsEnvironmentError: The environment has not been configured to use Netlify Blobs. To use it manually, supply the following properties when creating a store: siteID, token",
    "    at getClientOptions (file:///var/task/node_modules/@netlify/blobs/dist/chunk-SGXOM2EY.js:298:11)",
    "    at getStore (file:///var/task/node_modules/@netlify/blobs/dist/main.js:294:27)",
    "    at file:///var/task/netlify/functions/my-cool-function.mjs:156:17",
    "    at ModuleJob.run (node:internal/modules/esm/module_job:222:25)",
    "    at async ModuleLoader.import (node:internal/modules/esm/loader:323:24)",
    "    at async _tryAwaitImport (file:///var/runtime/index.mjs:1008:16)",
    "    at async _tryRequire (file:///var/runtime/index.mjs:1057:86)",
    "    at async _loadUserApp (file:///var/runtime/index.mjs:1081:16)",
    "    at async UserFunction.js.module.exports.load (file:///var/runtime/index.mjs:1119:21)",
    "    at async start (file:///var/runtime/index.mjs:1282:23)"
  ]
}

To fix this, getStore needs to happen within a function called by a request.

For internal tracking, this was first reported: https://linear.app/netlify/issue/FRP-985/ and has been fixed as of: https://linear.app/netlify/issue/FRP-959/.

The only difference is that, there getStore was being called during build time and here, based on the stack trace, this looks to be happening within a Function. I don't think the fix was for that part.

What's the use-case here? Any particular reason to call getStore outside of the default export?
