Add support to query local copies of a codebase rather than relying on GitHub's APIs

@julianharty Creating a placeholder issue for this work. For more details please see the earlier ticket #7 which presents a range of approaches.

created a branch 37-add-support-to-query-local-copies-of-a-codebase-rather-than-relying-on-githubs-apis created a script src/github_repo_request_local.py wrote the script to clone a repo from a csv and count the file names/path which has the word test in them was getting an error for the pre-commit stages when tried to push the code, had to run : ruff check github_repo_request_local.py and pre-commit run --all-filesmanually and then was able to push the code to the branch

• used pathlib package for getting the result
• excluded some file extensions from the result ({'.txt', '.md', '.h', '.xml', '.html', '.json'})
• realised the parent path is counted into the result . Addressed this
• running the script for the first 20 repos
• comparing the result with the script I wrote using the github API, I see some differences.
• there are some .png and .jpg files that are counted -> will exclude them
• there are lot's of .kt files which are counted in the new script in the previous script the test count is 0 but in the new script it is 263 . .kt extension which is commonly known as Kotlin file extension. The Kotlin is a general-purpose cross-platform programming language developed by JetBrains to be fully interoperable with Java. The Kotlin trademark is protected by the Kotlin Foundation.
• for some repos I had github API count = 0, but in the new script I have the local count :4 (files are: cloned_repos/reload/tests/peer_link, cloned_repos/reload/tests/test_dtls.py, cloned_repos/reload/tests/test_message_types.py, cloned_repos/reload/docs/testing.rst)
• seems like the new script is more reliable
• as I had to run the code multiple times (ran out f space on my hard disk,..) I changed the code to be able to resume the work where it has stopped in the last run
• cannot open the default editor in git when trying to put a multiple line commit message--> fix is git config --global core.editor nano
• script finished running
• investigating the results : some usernames have changed (warner/magic-wormhole changed to magic-wormhole/magic-wormhole ) and the previous script was not able to count the files but this issue is addressed with the new approach (downloading the repo locally)
• Have pushed the code to my branch and raised a PR
