fix(cicd): create releases with the release PAT on core/1.47 (#15447)

## Problem

`release-draft-create.yaml` is triggered by `pull_request: closed`, so
it runs from **the base branch's own copy** of the workflow. #15003
switched Create Release to `secrets.PR_GH_TOKEN` on `main` on
2026-08-10, but that fix was never backported, so `core/1.47` through
`core/1.50` still pass `GITHUB_TOKEN`.

`GITHUB_TOKEN` is refused with `403 Resource not accessible by
integration` when creating a release on a `core/*` line, so every patch
cut from these branches fails at the tag step.

This is not theoretical. Run
[31929089801](https://github.com/Comfy-Org/ComfyUI_frontend/actions/runs/31929089801)
cut `1.49.7`, the bump PR merged, and `v1.49.7` was never created.
`core/1.49` has sat at `package.json` 1.49.7 with `v1.49.6` as its
newest tag since 2026-08-16, and ComfyUI pins 1.49.6 — so 1.49.7 and the
#15211 popular-templates backport have not reached users.

## Fix

Same one-line change as #15003, applied to this line.

Companion PRs cover the other affected branches: core/1.47, core/1.48,
core/1.49, core/1.50.

After this merges, `core/1.49` still needs its missing release recovered
with `release-recover-tag.yaml` (#15006).

## Test

`actionlint` and `scripts/cicd/check-yaml.sh` are clean on the changed
file. The two warnings they emit here (`SC2086` on line 34, and a
`comments-indentation` hit in `ci-tests-e2e.yaml`) are pre-existing and
reproduce without this change.
