Rollup merge of #142639 - dpaoliello:needcolon, r=WaffleLapkin

Add a missing colon at the end of the panic ___location details in ___location-detail-unwrap-multiline.rs

The `___location-detail-unwrap-multiline` test was failing when trying to enable `aarch64-pc-windows-msvc` CI Runners: #140136 (comment)

When debugging, the normalized stderr was:

```
thread 'main' panicked at $DIR/___location-detail-unwrap-multiline.rs:11:10:
called `Option::unwrap()` on a `None` value
stack backtrace:
note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.
```

Note the trailing colon at the end of the ___location details in the panic message. This was missing in the error pattern regex. No idea why it has been passing for all other targets and failed for `aarch64-pc-windows-msvc`, but with the trailing colon it is now passing for all.
