Better error handling after Create draft PR or push branch workflow

[neubig]

Currently in the Create draft PR or push branch workflow, even if the workflow fails due to permission issues, etc., a comment is sometimes posted that the branch or PR was completed successfully.

openhands-resolver/.github/workflows/openhands-resolver.yml

Lines 62 to 81 in 32139d5

	- name: Create draft PR or push branch
	env:
	GITHUB_TOKEN: ${{ secrets.PAT_TOKEN }}

	run: |
	if [ "${{ steps.check_result.outputs.RESOLUTION_SUCCESS }}" == "true" ]; then
	python -m openhands_resolver.send_pull_request \
	--issue-number ${{ github.event.issue.number }} \
	--pr-type draft | tee pr_result.txt && \
	grep "draft created" pr_result.txt | sed 's/.*\///g' > pr_number.txt
	else
	python -m openhands_resolver.send_pull_request \
	--issue-number ${{ github.event.issue.number }} \
	--pr-type branch \
	--send-on-failure | tee branch_result.txt && \
	grep "branch created" branch_result.txt | sed 's/.*\///g; s/.expand=1//g' > branch_name.txt
	fi

We should check that the workflow actually succeeded by making sure that there is a non-empty value in prNumber or branchName, and if the workflow failed, write a message to that effect.

This is about github workflows, so we don't need python tests for it.
