Found X rules verbose message is misleading

[philsturgeon]

Describe the bug

If you disable rules by turning them off, the verbose message "Found 35 rules" still shows up, counting the total list of all rules that are known about even if they are disabled.

To Reproduce

Make a ruleset like this:

ruleset.yaml

extends: [[spectral:oas3, off]]

rules:
  only-local-references: true

Run

$ yarn spectral lint examples/openapi.yaml -v --ruleset=ruleset.yaml

Linting ./examples/openapi.yaml
Adding OpenAPI 3.x functions
Found 35 rules
No errors or warnings found!
Done in 1.33s.

Current behavior
CLI output contains Found 35 rules

Expected behavior
CLI output should contain Found 1 rule

Make sure its saying 1 rule not 1 rules

Environment (remove any that are not applicable):

• Library version: 4.0.2
• OS: [e.g. Windows 7]
• Browser: [e.g. Chrome 61]

Additional context

This came up in #434

I'd say, we should still say found 35 rules and additionally display how many of them are disabled, i.e.
found 35 rules (1 enabled).
Frankly speaking, if Found 1 rule text was printed, I would think there are no other rules in the ruleset while it's untrue - there are others, but they are just disabled.

This would fit me perfectly!
