Tags not sorted by semver version

**Describe the bug**

Repositories utilizing `--base-branch` to do hot fixes can see tags created "out of order" where you may have tags like:
```
latest: 2.5.1
previous: 3.0.0
```

In this case, when releasing a new version, auto gets the most recent created tag:
https://github.com/intuit/auto/blob/main/packages/core/src/git.ts#L890

And calculates the changelog/version bump based on that version, rather than the latest semver version for the specified branch.

**To Reproduce**

- Release multiple major or minor versions
- use `--base-branch` to release a hotfix to an older version
- release a new version from the main branch
- the changelog will show the diff between the hotfix and HEAD, rather than the latest tag for the main branch and HEAD

**Expected behavior**

The changelog should only calculate based on the latest tag for the main branch
