Pages URL Not GHES Friendly

[amyschoen]

The pages URL is hard-coded to only work for .com. It needs to be corrected for GHES.

https://github.com/githubtraining/introduction-to-github/blob/master/responses/reminder-delete.md

I don't know the proper variables but it's likely to be something similar to what we do in the scripts for the GitHub for Developers course unless there's a better way that would work for both. The info is being used in one of the earlier steps as {{ pagesUrl }}, but that is passed to the step in question and doesn't seem to persist.

.com: https://${CLASS_ORG}.github.io/${REPO_NAME}
GHES: https://${ROOT_URL}/pages/${CLASS_ORG}/${REPO_NAME}

Thanks for the report, @amyschoen! We can grab the URL from the API like we do in the config:

introduction-to-github/config.yml

Lines 86 to 95 in 5b30c5e

	- type: octokit
	method: repos.getPages
	owner: '%payload.repository.owner.login%'
	repo: '%payload.repository.name%'
	action_id: pagesUrl
	- type: respond
	issue: Getting Started with GitHub
	with: close-issue.md
	data:
	pagesUrl: '%actions.pagesUrl.data.html_url%'

Nice. The variables aren't well published. It'll be nice to not have to bring in changes to the repo every time we upgrade locally.
