`orb-tools/pack` fails if boolean parameter's default value is other than `true` or `false`

Orb version:

11.1.2

What happened:

According to the CircleCI documentation, boolean parameters can have the following values: y yes true on n no false off

However, if a command parameter is declared as a boolean with a default value other than true or false, the "Validating orb" step fails with:

Parameter error: default value of parameter '<parameter_name>' is 'on' (type string): expected type boolean

Expected behavior:

The "Validating orb" step should pass if the boolean default value is any of: y yes true on n no false off

Additional Information:

Using:

circleci version
0.1.17183+341e493 (homebrew)

Locally running, circleci orb pack src > orb.yml then circleci orb validate orb.yml produces the same output:
```
Parameter error: default value of parameter 'killswitch' is 'on' (type string): expected type boolean
```

And the generated orb.yml contains a string value:

        parameters:
            killswitch:
                default: "on"
                type: boolean

However, locally running circleci config validate on the below configuration file is successful:
```
version: 2.1
```

jobs:
build: parameters: killswitch: type: boolean default: on machine: image: ubuntu-2004:202201-02 steps:

run: shell: bash environment: KILLSWITCH: << parameters.killswitch >>
command: | echo $KILLSWITCH workflows: build-and-release: jobs:
- build: killswitch: off

I suspect the issue is caused by the use of "gopkg.in/yaml.v3" in https://github.com/CircleCI-Public/circleci-cli/blob/master/cmd/config.go#L17.

Specifically, as of v3 of the yaml package:

YAML 1.1 bools (yes/no, on/off) are supported as long as they are being decoded into a typed bool value. Otherwise they behave as a string. Booleans in YAML 1.2 are true/false only.

(Reference: https://pkg.go.dev/gopkg.in/yaml.v3#readme-compatibility)
