[PATCH] t1900: add tests for git repo structure subcommand

["Mansi Singh via GitGitGadget" <gitgitgadget@gmail.com>]

From: Mansi Singh <mansimaanu8627@gmail.com>

The t1900 test file covers git repo info thoroughly but has
no tests for the git repo structure subcommand. Add basic
tests to verify that:

- git repo structure succeeds and produces no stderr output
- git repo structure --format=keyvalue outputs expected keys
- git repo structure --format=nul succeeds
- git repo structure rejects an unknown format

    t1900: add tests for git repo structure subcommand
    
    Add tests for the git repo structure subcommand in t1900-repo-info.sh.
    The tests verify that git repo structure outputs the expected fields
    (commits, trees, blobs, tags) in both default and key-value formats.
