Update build and pack steps in dotnet.yml workflow

- Set the build version dynamically using the GitHub run number
- Update the sed command to replace the version in PROJECT_FILE with the GitHub run number
- Modify the pack step to include VersionPrefix and ReleaseNotes parameters from GitHub event release tag name and body respectively

Update LlamaIndex.Core.csproj and LlamaParse.csproj files

- Change the Version property to use $(VersionPrefix) variable instead of hardcoding it as 0.0.0
