Add missing attributes and nodeset entry to Zuul schema (SchemaStore#5225)

* Add group-vars attribute to Zuul job schema

Add support for the group-vars job attribute which allows setting
Ansible variables for groups of nodes. This mirrors the existing
host-vars attribute but applies to inventory groups instead.

* Add merge-mode attribute to Zuul project schema

merge strategy used by Git. Valid values are: merge, merge-resolve,
merge-recursive, merge-ort, cherry-pick, squash-merge, and rebase.

* Add nodeset entry type to Zuul schema

Add support for top-level nodeset definitions in Zuul configuration files.
A nodeset defines a collection of nodes and groups for use by jobs.

The schema supports:
- nodes: List of node definitions with name and label
- groups: List of group definitions for organizing nodes
- alternatives: List of fallback nodesets to try in sequence
