Fast-ci.yaml's PostResult job can't handle the character ' in the branch name.

[nick4598]

It seems if the branch name contains the character ', then it gets ignored when the PostResult job runs in fast-ci.yaml

itwinjs-core/common/config/azure-pipelines/jobs/fast-ci.yaml

Lines 147 to 170 in d8b4364

	- job: PostResult
	dependsOn:
	- CheckLinkedPR
	- Build
	condition: and(succeeded(), eq(dependencies.CheckLinkedPR.outputs['checkForPr.POST_STATUS'], 'true'), eq(variables['Build.Reason'], 'PullRequest'))
	displayName: Post Success
	pool:
	vmImage: ubuntu-latest
	steps:
	- bash: |
	branch=$(System.PullRequest.SourceBranch)
	sha=$(gh pr view $branch --json "headRefOid" -q ".headRefOid")
	echo "Posting 'success' status to current PR"
	gh api \
	--method POST \
	-H "Accept: application/vnd.github+json" \
	/repos/$(Build.Repository.Name)/statuses/$sha \
	-f state='success' \
	-f target_url='$(BUILD_URL)' \
	-f context='itwinjs-core PR validation' \
	-f description='No native PR was linked'
	env:
	GITHUB_TOKEN: $(GH_TOKEN)

This results in a 404 as seen below:

If git allows ' in the branch name, then our PostResult job should also handle it. After looking at the yaml step more closely though, its possible $(System.PullRequest.SourceBranch) is actually where the bug is occurring. In that case it may be out of our control.
