Docs: Update existing sample output of TermiFlow

[tecnolgd]

• Currently the GIF assets/termiflow.GIF displays the outputs for the version of TermiFlow which is no longer the latest version.
• Therefore, an updated GIF with respect to the latest working outputs of TermiFlow is recommended to be added to the README.

Note: The size of the GIF file is expected to not change or increase with the updated GIF.

Closed via #72 to avoid maintenance overhead of handling GIF files.
