Fix for bug with accepting FormData as body

- Added .eslintignore file.
- Updated the .eslintrc.json file.
- Updated depencencies.
- Reconfigured the transportr.tests.js file to use test.concurrent.
- Added a test to check if the request body is removed when the request method is GET.
- Added code to remove the content-type header and request body if the request method is GET.
- Changed the private methods to use regular objects instead of FormData, Headers, and URLSearchParams.
- Added a check for the response in the catch block of the fetch call to ensure that another error isn't thrown.
