Issue: Generated readme replaces repo's readme file

[Mounayer]

Description

When I ran the rm-generator generate main.cpp command, the generated README.md file replaced the project's README.md file. Perhaps there should be a functionality that modifies the name of the generated file to something like FILENAME_README.md instead of just README.md.

Reproducing The Issue

• Create any source code file in the current repository, i.e. main.cpp.
• Run rm-generator generate main.cpp
• Verify that the repository's README.md file has been replaced with a new README.md file explaining the main.cpp file that was processed

Fix Suggestion

For now, maybe simply updating the name of the file generated in index.js from:

const outputPath = path.join(fileDir, "README.md");

to

const outputPath = path.join(fileDir, `${file}_README.md`);

Thank you for catching this.

I wrote the code with the assumption that the user will be passing files from a different directory when using the tool. This also provided me an idea for a possible feature in the future!
