Issue:
Support GNU style file:line.column links
The [Sail compiler]() outputs file:line links that follow [this GNU convention](https://www.gnu.org/prep/standards/html_node/Errors.html):

```
Warning: Redundant case sail-riscv/model/riscv_sys_control.sail:206.6-7:
206 |      _ => false
    |      ^
```

This doesn't currently work in VSCode. It does support a very wide range of formats and I don't recall ever seeing this format before (even from GNU tools) so I suspect nobody else uses it. Nonetheless it's easy to add support in VSCode.

Discussion:
Doesn't seem to work, see `echo src/vs/workbench/contrib/snippets/browser/snippetsFile.ts:70.30-36`

The PR intentionally left that out:

But it should be easy to add so will leave this open.
