Detect file paths that end with : (#3109)

New rustc messages look like

```
thread 'tests::test_history_items_vs_very_good_external_match' panicked at crates/file_finder/src/file_finder.rs:1902:13:
assertion `left == right` failed: Only one history item contains collab_ui, it should be present and others should be filtered out
  left: 0
 right: 1
```

now and we fail to parse that `13:` bit properly, fix that.

One caveat is that we highlight the entire word including the trailing
`:`:
<img width="914" alt="image"
src="https://github.com/zed-industries/zed/assets/2690773/d653a8ff-3e6e-4e3d-b6ea-dad0c8db0f06">

this is unfortunate, but better than nothing (as now).
This is due to the fact, that we detect words with regex inside the
`terminal.rs` and send events to other place that's able to check paths
for existence (and whether that's a path at all), currently there's no
way to detect a path and sanitize it in `terminal.rs`

Release Notes:

- N/A
