Fix Graphql/Descriptions EE types offenses

https://gitlab.com/gitlab-org/gitlab/-/merge_requests/46721 introduced a
new rubocop that enforced periods at the end of GraphQL description
strings. Existing offenses were added to `.rubocop_manual_todo.yml`.

This change fixes roughly half of the offenses in `ee/app/graphql/types`
and `ee/app/graphql/ee/types` and removes the exclusion of them from
`.rubocop_manual_todo.yml`.

The changes were generated using the following autocorrect:

    bundle exec rubocop app/graphql \
      --auto-correct \
      --only Graphql/Descriptions
