feat(typescript-estree): add new node type TSUnknownJSDocType

[armano2]

This node can be produced only in few cases when code has invalid syntax

export interface TSUnknownJSDocType extends BaseNode {
  type: AST_NODE_TYPES.TSUnknownJSDocType;
  kind:
    | 'JSDocAllType'
    | 'JSDocUnknownType'
    | 'JSDocFunctionType'
    | 'JSDocNullableType'
    | 'JSDocNonNullableType';
  value: string;
}

I'm not sure about name, TSUnknownJSDocType, TSInvalidJSDocType or more generic TSInvalidType
