[Error page] skipLink variable is missing from Error.tsx

[giorgoslytos]

This is a minor issue, but there are some cases that it might be useful.
When we navigate, for example to an invalid url and get 404 and the client_id is not provided, in the original keycloak theme there is a variable skipLink which is true in such cases but it is not provided from the kcContext and it is not used in Error.tsx.

As a result baseUrl will be undefined have faulty behavior.
