Adds a warning in the tutorial's Object Database section (doc/source/tutorial.rst, line 515) about GitDB failing or running extremely slowly when traversing trees in repositories with very large commits. Directs users to use GitCmdObjectDB instead. Closes #2065. This contribution was developed with AI assistance (Claude Code).

Sorry, something went wrong.

Uh oh!

Add a warning note in the Object Database section of the tutorial
about GitDB failing or becoming extremely slow when traversing trees
in repositories with very large commits (thousands of changed files).
Directs users to switch to GitCmdObjectDB instead.

Closes gitpython-developers#2065
