In docs, update query packs references to Teams + Schedule

[noahtalerman]

Goal

In the Fleet documentation and articles, replace references to query packs with references to Teams and Schedule features so that anyone visiting the docs sees that "Teams" are best practice for targeting groups of computers.

Removing this from the release board because it cannot be addressed until #7765 and #6024 are addressed.
