Error message for tag not found is not specific enough

[LowXiSi]

Error message for tag not found when using untag command is not specific enough. The user will have to search through all the tags to find out which tag is not found in the person's tag list. This can be hard to spot and cause an inconvenience if it was a minor spelling error.

steps to reproduce:
Ensure contact 1 on the list has the tags Tag1, photographer, and gardener.
Try: untag 1 t/Tag1 t/photographer t/garderner
expected: garderner was not found in the person's tag list.
actual: Some tags were not found in the person's tag list.

Team's Response

The user would likely have to look at a contact's list of tags when untagging and, regardless of how many tags they are currently tagged with, all are shown in the Person card. Hence, they would not have to scroll through the list of all tags to find their mistake. This could be improved by making the error message be more specific, but this fix is not in scope.
