fix: Allow github.com auth when github-enterprise.uri is set

[dyhagho]

Problem

Since version 0.110.0, setting the following configuration:

"github-enterprise.uri": "https://someghe.com"

causes the github.com authentication flow to be skipped entirely. This results in:

• No prompt to authenticate with github.com
• Pull Request extension for github.com repos breaking silently

For many developers (including myself), contributing to both github.com and a company-hosted GitHub Enterprise is common.

Even though the config can be set per workspace, it can be tedious to maintain across multiple repositories.
And, in practice, setting github-enterprise.uri in user settings makes more sense. But this intentionally disables github.com functionality with the current logic.

What does change?

This PR updates doCreate so that github.com is initialized even though the enterprise URI is configured.
This mirrors pre-0.110.0 behavior.
