Can't find lockfile entry for non semver compliant packages when using yarn

When trying to add patch for package that has non semver compliant version in its package.json patch generation throws error:
```
Can't find lockfile entry for ...
```

For example:
plugin `serverless-plugin-aws-alerts` has version specified as `v1.7.4`, while in `yarn.lock` it's saved as `1.7.4`. Because of this entry from `yarn.lock` is filtered out in following code:

```typescript
const entries = Object.entries(appLockFile.object).filter(
([k, v]) =>
k.startsWith(packageDetails.name + "@") &&
v.version === installedVersion,
)
```

Potential solution that I would like to propose is to coerce versions (`semver.coerce`) while searching for lockfile entry in `yarn.lock`.
