Fix Dockerfile paths to match updated folder structure

The `COPY` commands were updated to remove the "src/" prefix, as the project folders (e.g., `GymMgmt.Api`, `GymMgmt.Application`) are located at the root level. This ensures the correct files are copied during the build process.

The `RUN dotnet restore` command was adjusted to reflect the new path for the `GymMgmt.Api.csproj` file, removing the "src/" prefix.

The `WORKDIR` for the build and publish step was updated from `/src/src/GymMgmt.Api` to `/src/GymMgmt.Api`, eliminating the redundant "src/" directory.

These changes resolve path mismatches, ensuring the Docker build process runs reliably.
