docs(merge-protections): documents the two other things that stop auto_merge_conditions working

[mergify-ci-bot]

The Constraints section listed what auto_merge_conditions cannot be combined
with, but not what it requires. Enabling it on a repository that does not have
Merge Protections turned on is accepted by the configuration validator and then
does nothing at all — the engine checks the product is enabled before it acts,
independently of whether a merge queue exists. That is a quiet failure: the
configuration is valid, no error is reported, and pull requests simply are not
merged.

Adds a sentence stating the prerequisite and pointing at the page that covers
enabling the product.

Evidence: the engine's auto-merge gate, which returns false unless Merge
Protections is among the repository's enabled products.

🤖 I read this review and pushed a new revision.

Trimmed, per Julian's point. The paragraph about the deprecated auto_merge
boolean and its migration pull request is gone, and the autoqueue sentence is
restored to what it says on main.

The diff is now a single added paragraph: auto_merge_conditions only takes
effect when Merge Protections is enabled on the repository, with or without a
merge queue. That one is worth keeping — it is a constraint on the key the page
is about, not on a key being retired, and it is the quiet failure mode where the
configuration validates and then nothing happens.
