Normal users can't create first snippet in Enterprise version

[paoliniluis]

Describe the bug
On a brand new Enterprise install, users don't have the ability to create snippets by default.
In addition, in order to grant access, an admin has to first create a snippet, then change the root permissions.

Logs
NA

To Reproduce

1. Set up a new instance on Enterprise
2. create a normal user
3. logged in as the normal user, try to create the first snippet, see the error

Expected behavior
Unless there's an explicit permission set by an administrator, normal users should be able to create a snippet

@paoliniluis and @flamber this was labeled as Type:New Feature back in the EE days. There is even a test that made sure this behavior is currently expected.
https://github.com/metabase/metabase/blob/master/frontend/test/metabase/scenarios/native/snippets/snippet-permissions.cy.spec.js#L32:L51

Also, look at the comment in this spec:

@nemanjaglumac Things have changed. EE build is being used elsewhere. This should always have been a bug.
