Rollup merge of #119184 - Rajveer100:branch-for-issue-118752, r=davidtwco

Switch from using `//~ERROR` annotations with `--error-format` to `error-pattern`

Fixes #118752

As noticed by ```@jyn514``` while working on a patch, tests failed due to `//~ERROR` annotations used in combination with the older `--error-format` which is now `error-pattern`.
