How to test locally

1. See changes made on the gitops-engine repo

2. checkout to this PR

3. Add this line at the bottom of the go.mod file:
   replace github.com/argoproj/gitops-engine => github.com/aali309/gitops-engine ffd6fbbdf5070252b41ab984b3cc19c7fc4442d7

4. run make mod-download-local && make mod-vendor-local

this should change the above added replace github...... to something similar to the below screenshot

5. Run the server locally and make changes to any immutable fields and try to sync. The error should provide the exact field that was changed with the old and new values.
