Subject: [PATCH] docs: add license files for checkpoint-sqlite and
 checkpoint-postgres (#6392)

In this PR:

- Add missing LICENSE files for checkpoint-sqlite and
checkpoint-postgres libraries.

Both libraries specify the MIT License in their pyproject.toml files,
but the actual LICENSE files were missing.
This update adds the corresponding LICENSE files to ensure proper
license documentation and compliance.
