GitHub: Renovate attempts to reopen deleted Dashboard issue

[rarkins]

Describe the proposed change(s).

Discussion: #32161

Workaround: change dependencyDashboardTitle

It would be good to strongly type Issue state to achieve this, e.g.

diff --git a/lib/modules/platform/types.ts b/lib/modules/platform/types.ts
index 91575d098..24eb42cba 100644
--- a/lib/modules/platform/types.ts

This issue will only occur when the repository cache is enabled. Because the deleted issue never gets removed from cache as the graphql api never returns any update data for the issue saying it's deleted, hance our cache stores the deleted issue as it was either open/closed.

Won't happen when cache is disabled cause we fetch the issues each time and deleted issues don't get returned in that api call.

We need to catch the error during getIssue() and check for the statusCode=410 and then remove the issue from cache or change its state to deleted and update cache.

Filtering is already done for state=open. Hence, the deleted issue will never be passed forward from findIssue
