ci: dont annotate the git tag

We kind of have two options here, provide an additional message
for the `-a` tag or add an addtional message with the `-m` argument.

From the help message:
```
-a, --annotate        annotated tag, needs a message
```

I opted for removing it but if you feel like we should rather add a message let me know
