env(.filename) doesn't always exist

[NullVoxPopuli]

this is maybe user-error, but if you specify the template transform like this:

    [
      "babel-plugin-ember-template-compilation",
      {
        "targetFormat": "hbs",
        "transforms": [
          ["glimmer-scoped-css/ast-transform"],
        ]
      }
    ],

you get an error:

[!] (plugin babel) TypeError: <repo>/src/index.ts: Cannot read properties of undefined (reading 'filename')

src/index.ts
    at <.pnpm>/glimmer-scoped-css@0.8.1/node_modules/glimmer-scoped-css/src/ast-transform.ts:30:11

The plugin must be specified like this:

    [
      "babel-plugin-ember-template-compilation",
      {
        "targetFormat": "hbs",
        "transforms": [
          ["glimmer-scoped-css/ast-transform", {}],
        ]
      }
    ],

or, as documented:

    [
      "babel-plugin-ember-template-compilation",
      {
        "targetFormat": "hbs",
        "transforms": [
          "glimmer-scoped-css/ast-transform",
        ]
      }
    ],
