Github workflow misattributes /cherry-pick backport request comment

[patrick-rivos]

Request: #82430 (comment)
Misattributed to me: #82572

Current workflow:

llvm-project/.github/workflows/issue-release-workflow.yml

Line 68 in 815644b

--requested-by ${{ github.event.issue.user.login }} \

Replacing this line with ${{ github.event.comment.user.login }} would attribute the PR to the user that commented /cherry-pick

From looking at the workflow it looks like it supports cherry-pick in newly opened issues too. Replacing the .issue with .comment won't work in that case, so issues/comments need to have different logic to attribute properly in all cases.
