[Feat]: Workflow for closing issues on merging PR linked to that issue

[Asymtode712]

Describe the solution you'd like

As the repo maintainers have to manually close an issue after merging a PR linked with that issue, I propose a workflow where the issue linked with a PR which be automatically closed when that PR is merged by the maintainer and efforts will be saved.
