Type errors with TypeScript 5.4+

[freben]

When upgrading to TypeScript 5.4+, importing from ast-types leads to type errors.

Reproduction:

• check out https://github.com/backstage/backstage/pull/24265
• run yarn install
• run yarn tsc:full

Result:

Obeying the instructions and explicitly making them type imports solves the problem:

-import { ASTNode, Type, AnyType, Field } from "./lib/types";
+import { ASTNode, type Type, AnyType, Field } from "./lib/types";
-import { NodePath } from "./lib/node-path";
+import { type NodePath } from "./lib/node-path";
-import { builders } from "./gen/builders";
+import { type builders } from "./gen/builders";
