install-runhcs-shim: fetch target commit instead of tags

fuweid · k8s-infra-cherrypick-robot · commit 42bb71e1e5bd · 2025-08-30T05:11:03.000Z
No idea why it blames lock during fetching.

```bash
...
 * [new tag]           v0.9.9           -&gt; v0.9.9
error: cannot lock ref 'refs/tags/v0.6.3': Unable to create 'C:/Users/runneradmin/AppData/Local/Temp/tmp.N2FTxfARN9/.git/refs/tags/v0.6.3.lock': File exists.

Another git process seems to be running in this repository, e.g.
an editor opened by 'git commit'. Please make sure all processes
are terminated then try again. If it still fails, a git process
may have crashed in this repository earlier:
remove the file manually to continue.
+ cleanup
+ rm -rf /tmp/tmp.N2FTxfARN9
```
