Subject: [PATCH] Fix bin/root-tag when applied to annotated tags (#4299)

Fixes #4298

Since we started using using annotated tags for releases (because they
need to be signed), `bin/root-tag` will append `^0` to them when used
after checking out a release tag. E.g.:

```
$ bin/root-tag
edge-20.4.4^0
```

which breaks version checking by the CLI.

This PR removes that trailing `^0` whenever it's present
