`$$Generic`s are treated as `any` by typescript-eslint

[DetachHead]

Describe the bug

the typescript-eslint plugin seems to not be aware of $$Generic, and treats them as any.

Reproduction

1. enable @typescript-eslint/no-unsafe-member-access and @typescript-eslint/no-unsafe-call in your eslint config
2. create a .svelte file with the following contents:

   <script lang="ts">
       type T = $$Generic<number>
   
       export let foo: T
   
       // Unsafe member access .toString on an `any` value. (@typescript-eslint/no-unsafe-member-access)
       // Unsafe call of an `any` typed value. (@typescript-eslint/no-unsafe-call)
       foo.toString()
   </script>

Expected behaviour

no errors as T extends number so it cannot be any

System Info

• OS: windows 10
• IDE: vscode

Which package is the issue about?

svelte-language-server

Additional Information, eg. Screenshots

probably related to #1778, i assume typescript is just treating it as any in both cases

[dummdidumm]

typescript-eslint is not under our control and unrelated to this repository, therefore closing

But $$Generic is part of svelte, so I doubt the typescript-eslint maintainers would care either.

Hopefully when #1778 is fixed it will fix this issue as well
