fix: Add Type validation for get/set method

[kamiazya]

What was a problem

The type check of the value corresponding to the key of the set method was not performed.

graph.attributes.edge.set(attribute.color, 's'); // it should be error, but it is not error

How this PR fixes the problem

This PR fixes the problem by adding a type check to the set method.

export interface Attributes<T extends AttributeKey> {
  ...
  get<K extends T>(key: K): Attribute<K> | undefined;
  set<K extends T>(key: K, value: Attribute<K>): void;
  ...
}
