Add missing feature_category to two specs

What does this MR do and why?

Adds feature_category to two specs. These particular two are spamming when we run the Category:Remote Development spec suite.

As far as I can tell these belong in https://docs.gitlab.com/ee/development/feature_categorization/index.html#shared-feature-category
