Request to Access Playground After GitHub Account Change

### What problem are you trying to solve?

I changed my GitHub personal account to an organization account, and as a result, I can no longer log in to Deno Deploy.

My new personal account is a member of the organization account. I would like to access the Playground that was created under the organization account when I log in with my new personal account.

I’m not very familiar with how GitHub account integration works, so I apologize if I’m saying something incorrect.

GitHub provides a feature to convert a personal account into an organization account, which cannot be used for GitHub login.
In cases like Deno Deploy, where account creation and authentication rely solely on GitHub login (integration), this kind of issue can occur.

### Describe the solution you'd like

Allow access to Deno Deploy created under the organization account when logged in with the new personal account.

### Describe alternatives you've considered

Since the GitHub account used to create the Deno Deploy account has been converted into an organization account, access to the Deno Deploy account is no longer possible. Therefore, it is not even possible to consider alternative solutions.
