Issue:
Incorrect commit message for version bumps
When running `auto shipit` using lerna, my commit message ends up being `Bump version to: %v [skip ci]` instead of `Bump version to: v.2.0.0 [skip ci]`

Looks like the problem is here: https://github.com/intuit/auto/blob/dbffbefcf35e902e22e654df9b28b4c7255d2599/plugins/npm/src/index.ts#L448

```js
          "'Bump version to: %v [skip ci]'",
```
should be 
```js
          '"Bump version to: %v [skip ci]"',
```
(note the first snippet has single quotes surrounded by double quotes, preventing the version from being properly interpolated)

Pull request description:
Fixed string interpolation on Lerna version bump
resolves #692
