fix: make the account id optional when getting plans

[joshghent]

This means that a user doesn't need to be logged in to view plans.
The docs for this endpoint describe the account_id being optional but sending null or not providing this argument causes an error to be thrown. https://usebasejump.com/docs/billing#get-plans

Apologies, i've added a load of testing commits to this! Will fix this :)

Hi @joshghent - how are you currently packaging your fork? Would be good to get my hands on this while we wait for the merge. Cheers

@jfloodnet update the import for this repo in billing-functions/index.ts and billing-webhooks/index.ts like this

before

import {
    billingEndpoint,
    stripeBillingEndpoint
} from "https://deno.land/x/basejump@v2.0.3/billing-functions/mod.ts";

after

import {
  billingWebhooksWrapper,
  stripeWebhookHandler,
} from "https://raw.githubusercontent.com/joshghent/basejump-deno-packages/fix/account-id-optional/billing-functions/mod.ts";

Then just deploy the functions again with supabase deploy.
