fix: create_pr_if_not_exists check for closed/merged branches too

[jluque0101]

Description

Fixes an issue where a duplicate changelog PR is created immediately after merging an existing changelog PR into a release branch.

Problem

When a changelog PR (e.g., release/13.14.1-Changelog) is merged:

1. A push event fires to the release branch
2. The update-release-changelog workflow triggers
3. create_pr_if_not_exists() checks for existing PRs using gh pr list
4. Bug: gh pr list only returns open PRs by default — the merged PR is not found
5. A duplicate changelog PR is created

Solution

Added --state all flag to gh pr list commands in create_pr_if_not_exists() to include merged/closed PRs in the search.

Tested here: https://github.com/consensys-test/metamask-extension-infra-3257/actions/runs/21397035008/job/61709774559

Note

Low Risk
Low risk shell script change that only broadens PR existence checks in GitHub CLI calls; main risk is unexpected behavior if multiple historical PRs match the same head name.

Overview
Prevents release automation from creating duplicate PRs by updating create_pr_if_not_exists() in .github/scripts/utils.sh to have gh pr list include closed and merged PRs via --state all when checking for an existing PR.

The linked test somehow took 54 minutes to run https://github.com/consensys-test/metamask-extension-infra-3257/actions/runs/21397035008/job/61709774559

Is that because it's trying to construct a CHANGELOG from the beginning of time?

hey @HowardBraham , yes that's a side effect of testing in a fork and not related to the change itself.
We would get the same behavior even with the current version of the github-tools.
