Make --version report post release tag version

ATM I believe it reports only the tag

```

```

so it makes it unclear which actual version from `pip install -e` installation we had been running. Should be similar to e.g. how we do in `dandi-cli`:

```
❯ dandi --version
0.69.3+17.g03b7c072
❯ git describe
0.69.3-17-g03b7c072
```
