Core: Added the `index.query.parse.allow_unmapped_fields` setting to fail queries if they refer to unmapped fields. The percolator and filters in aliases by default enforce strict query parsing. Closes #7335

[DOCS] Remove major release references from migration guide (#83555) Updates the language in our migration guides to remove references to major releases.

As {es} introduces new features and improves existing ones, the changes
sometimes make older settings, APIs, and parameters obsolete. We typically
deprecate obsolete functionality as part of a release. If possible, we support
the deprecated functionality for several subsequent releases before removing it.
This enables applications to continue working unchanged while you prepare to
migrate away from the deprecated functionality.
To get the most out of {es} and facilitate future upgrades, we strongly
encourage migrating away from using deprecated functionality as soon as
possible.

To give you insight into what deprecated features you're using, {es}:
- Returns a `Warn` HTTP header whenever you
submit a request that uses deprecated functionality.
- <<deprecation-logging, Logs deprecation warnings>> when
deprecated functionality is used.
- <<migration-api-deprecation, Provides a deprecation info API>>
that scans a cluster's configuration
and mappings for deprecated functionality.
For more information about {minor-version},
see the <<release-highlights>> and <<es-release-notes>>.

Remove last few mentions of Zen discovery (#80410) We have a few leftover mentions of `zen` discovery, mostly for historical/BwC reasons, which this commit removes. Prior to this commit the default value for `discovery.type` was `zen` but this was not written down anywhere or officially supported: the two options were to set it to `single-node` or to omit it entirely. This commit changes the default to `multi-node` and documents this. Co-authored-by: Adam Locke <adam.locke@elastic.co>
