chore(deps): bump github.com/pb33f/libopenapi from 0.37.3 to 0.38.1 in /codegen

[dependabot]

Bumps github.com/pb33f/libopenapi from 0.37.3 to 0.38.1.

Release notes

Sourced from github.com/pb33f/libopenapi's releases.

v0.38.1

Fixes #590 and moved to our own fork of testify

v0.38.0

Improves parse/index performance and memory use with lazy SpecInfo JSON generation, lower-allocation node indexing, faster component-path conversion, and reduced goroutine overhead in small translation/schema paths.

Adds SkipMetadataCollection for consumers that do not need diagnostic index metadata, allowing faster/lighter parsing for large documents.

Tightens YAML handling around duplicate keys, merge/root errors, empty overlays, and YAML v4 rc.5 rendering behavior.

Fixes OpenAPI 3.0 webhooks extraction so same-named scalar values no longer create empty webhook maps.

Improves change detection and generator metadata fidelity, including anchor-insensitive YAML comparisons and preserved/inferred

YAML tags for generated enum/const metadata.
