fix(plugin): align test error expectations with context-sensitive validation messages

Update plugin_update_test.go so expected errors match the implementation:
non-v-prefixed versions no longer incorrectly expect the 'v' prefix
warning, and v-prefixed versions now include the full message with both
the range constraint notice and the 'v' prefix warning.
