Fix: Handle .git extensions in repository URLs

Fixing an error reported #32 (comment)

The main issue was that one of the plugins in the config file had a .git extension at the end of the repository URL.

awesome-nu/config.yaml

Line 235 in 65af689

url: https://github.com/pdenapo/nu_plugin_dpkgtable.git

To address this issue, we implemented two steps:

1. The script will now replace .git extensions with an empty string in URLs, ensuring that the script can correctly locate the Cargo.toml file.
2. If this issue arises again in the future, the script will handle it more robustly by omitting the affected plugin's data instead of crashing entirely.

Awe, I wondered if the data was corrupt. I looked but didn't see that. Thanks for fixing it.
