issue develop --base should result in pr create using that branch as the base later #10089

Description

This is split off from #8979 to indicate a slice of already delivered work.

The motivation for this work is that typically, when running issue develop --base, we are working against a long lived branch that isn't the default branch of the repo. When work is complete, we want it to be delivered back into this base branch.

Acceptance Criteria

Given I have begun developing an issue with gh issue develop --base long-lived
When I run gh pr create
Then the PR should be created with long-lived as the base
