readme.md needs to be changed to uppercase

[mysticaltech]

I got this error:

          getattr(self, attribute)
          ~~~~~~~^^^^^^^^^^^^^^^^^
        File "/home/karim/.cache/uv/builds-v0/.tmpW64yAI/lib64/python3.13/site-packages/hatchling/metadata/core.py", line 531, in
      readme
          raise OSError(message)
      OSError: Readme file does not exist: README.md

      hint: This usually indicates a problem with the package or the build environment.

It gets fixed just by issuing mv readme.md README.md

Hello, just add to your solution.

In the pyproject.toml file, the readme is specified as README.md with uppercase letters, but the actual file is readme.md with lowercase letters. Fix this by either:

• Renaming the existing file to match the name in pyproject.toml
  mv readme.md README.md

• Changing the specification in pyproject.toml to match the existing file.
  sed -i -e 's/readme.md/README.md/g' ./pyproject.toml

Regards!
