Peter Scheibel 621e203a8e Bugfix: spack config change handle string requirements (#42176) ...

For a requirement like

```
packages:
  foo:
    require:
    - "+debug"
```

(not `one_of:`, `any_of:`, or `spec:`)

`spack config change` would ignore the string. This was particularly evident if toggling a variant for a previously unmentioned package:

```
$ spack config change packages:foo:require:+debug
$ spack config change packages:foo:require:~debug
```

This fixes that and adds a test for it.
