[giti] `git log search`: Create a user experience for searching git log

[nazmulidris]

Here's the Kotlin version of this from years ago
https://github.com/r3bl-org/git-tools/tree/main/git-log-cli-kt

The idea is to allow users to be able to search their git logs. This can be to find things like renamed files in the history, or specific strings that are in the log messages, or even file names.

This is similar to what IDEA allows in its git history search.
