 Rename -Wmissing-monadfail-instance to plural-form

 This warning flag was recently introduced as part of #10751. However,
 it was missed during code-review that almost all existing warning
 flags use a plural-form, so for consistency this commit renames
 that warning flag to `-Wmissing-monadfail-instances`.

 Test Plan: local validate (still running)
