Fix pkgimages CLI error message to include 'existing' option (#60870) Fixes #60823 ## Problem The error message for invalid `--pkgimages` arguments was missing `existing` as a valid option. ## Solution Updated the error message in `src/jloptions.c` to include `existing` in the list of valid options. ### Before: ``` ERROR: julia: invalid argument to --pkgimages={yes|no} (exsiting) ``` ### After:  ``` ERROR: julia: invalid argument to --pkgimages={yes|no|existing} (exsiting) ``` --- **Note:** No AI tools were used.
