Change tags display name

Supported specification: OpenAPI. Note that OpenAPI 3.2 now supports summary on tags, behaving the same way as x-displayName.

The x-displayName property allows for custom tag names. When added, it replaces the default name value in the documentation.

tags:
  - name: myFirstTag
    x-displayName: Branches
  - name: mySecondTag
    x-displayName: Diffs
