Schema Inaccuracy

#/components/schemas/git-tree, which is git-tree response, says

        tree:
          description: Objects specifying a tree structure
          type: array
            type: object
            properties:
              mode:
                type: string
                example: '040000'
              type:
                type: string
                example: tree 

while "POST /repos/{owner}/{repo}/git/trees" has enums defined for request:

                  items:
                    type: object
                    properties:
                      mode:
                        type: string
                        description: The file mode; one of `100644` for file (blob),
                          `100755` for executable (blob), `040000` for subdirectory
                          (tree), `160000` for submodule (commit), or `120000` for
                          a blob that specifies the path of a symlink.
                        enum:
                        - '100644'
                        - '100755'
                        - '040000'
                        - '160000'
                        - '120000'
                      type:
                        type: string
                        description: Either `blob`, `tree`, or `commit`.
                        enum:
                        - blob
                        - tree
                        - commit

Expected

Request and response schemas are consistent, so response should also have enums defined.
