chore: sort issues by 'updated'

[nakamasato]

Description:

Use sort: updated when retrieving repository issues

As the default value of sort is created, when having many old issues, the retrieved issues are almost same until they're gradually closed, which is not efficient. https://docs.github.com/en/rest/issues/issues?apiVersion=2022-11-28#list-repository-issues

By changing the sort to updated, every execution can checks the least recently updated issues that would match the criteria used in this entire repo.

days-before-stale: The issues or the pull requests will be marked as stale if the last update
days-before-close: The issues or the pull requests will be closed if the last update
