Customize pr name

[ajorquera]

Preview URLs look like this: https://[owner].github.io/[repo]/pr-preview/pr-[number]/

Can we customized the path pr-[number]. Doesnt seem like we can

No, it's not currently possible.

Noting a possible use case: branch name in URL instead of PR number; previews might not necessarily be tied to PRs
