Add node version info, update github workflow, and resync package-lock

[anilnatha]

🗒️ Summary

• Added .nvmrc file to keep track of the NodeJS version this project relies on
• Updated README.md to help inform developers of NodeJS version dependency and how to work with those using nvm
• Updated gitignore to account for common python files that shouldn't be committed
• Rescyned package-lock.json because npm was complaining it was out of sync with our package.json file.
• Fixed version range information issue with react-scripts package. (this should also resolve one of our CI/CD build issues)
• Updated github workflow so that fail-fast is set to false so that all jobs in the matrix are run independent of one another. When this property it set to true, if any one job in the matrix fails, all other jobs are automatically terminated.

It's worth mentioning that the commits ab7a5a7 and e218c00 did help resolve issues with our Github workflow. The three tests now run independent of each other.

The test for Node 14.x and 16.x reports an issue after the build completes, but the underlying issue is unknown. The test for Node 18.x reports an incompatibility with version 18, which I also encountered when trying to run the application locally with any node version higher than 18.x.
