[#944] Implement authorship analysis (#2140)

A line is credited to the author who last modified it.

Another author might have written the line initially and the current
author only modified it slightly. In such a case, the current author
gets credited for work that is not entirely done by him/her.

Let's analyze how similar a line is as compared to its ancestor lines
(previous versions of the line) and give full or partial credit to the
last author based on the analysis.

[#1771] Add tip on generating report via reposense-action (#1858)

Generating RepoSense reports via GitHub Actions requires forking of the
template publish-RepoSense repo. It also only supports publishing with
GitHub Pages.

This process is more complicated than utilizing published actions on the
marketplace. It also requires direct edits to the script files for more
customization.

Let's document an available alternative via a community-published action
for interested users to explore.

The published action can be used in the same directory as the user's
project and support customization via action arguments. It also supports
surge.sh as an alternative publishing platform.
