issue-opened-dispatch.yml may use GET instead of POST for dispatch endpoint

Question

## Bug

.github/workflows/issue-opened-dispatch.yml line 24 uses gh api which defaults to GET method. The repos/TARGET_REPO/dispatches endpoint requires POST. While gh api sometimes auto-detects POST with -f flags, this is not guaranteed and could silently fail.
