fix: Update dist-pr.yml (#206)

Updates step to only fetch the ain branch, since dist-to-main-pr is being created locally off of the current HEAD. Attempt to fix this error:

pull request create failed: GraphQL: Head sha can't be blank, Base sha can't be blank, No commits between main and dist-to-main-pr, Head ref must be a branch (createPullRequest)
