cloc in template pulls latest XX commits to create history loc_plot

[yidilozdemir]

To save space, we made the cloc functionality only update for the latest hash entry, which works for scikit-surgery because we already have a past history. But in template, this means we have just pulled the repo at the latest commit, meaning we don't have any loc history to show in plots. So the plots are empty.

I should integrate a function that allows user to say, ex. latest 50 commits, or (improved version: last year, input a time frame) and get_loc in a loop pulls those repos and updates for that info.

I am seperating this from the earlier issue on integrating the cloc, because technically, what the issue flagged is established: get_loc is integrated into the template, fixed to work for user cases, and integrated into the GHA both for scikit-surgery deployment and for the template deployment
