[#436] Move the upload target to the top to expose it more

By rearranging the order of targets in the `config.mk` file, this commit
moves the `upload-config` target to a higher position within the file.
This adjustment is made to enhance visibility and accessibility to the
`upload-config` target, ensuring it is more prominent and easier to
locate for users working on deployment configurations.

Changes:
- Moved the `upload-config` target to the top of the `config.mk` file to
  improve visibility and exposure.
- No functionality changes were made; this adjustment aims to make the
  target more accessible within the file structure, enhancing developer
  workflow and understanding of the deployment makefiles.
