docs(readme): fix examples list formatting

[PSR94]

Summary

• Remove an orphaned example description line from the README examples list.
• Add the missing sentence-ending period to the Disentangled Sequential Variational Autoencoder entry.

Why this helps

• Keeps the README examples section easier to scan and avoids a dangling description that no longer has a linked example script.

Changes made

• Updated the example scripts list in README.md.

Testing

• git diff --check
• Verified README example list structure with a focused Python check.
• Verified linked example script files exist locally.

Related issue

• None.
