[vpc] Fix access to subnet details configmap

## What this PR does

The VPC chart incorrectly used the wrong template for the subjects that
should have access to the configmap info resource. This patch grants
this access to all subjects at or above a certain access level, rather
than just at a specific level.

### Release note

```release-note
[vpc] Grant read access to the subnets configmap to all users inside a
tenant.
```
