Add Permission-Based Access to Warps

[HonzasikCZ]

Problem Description

Currently, there's no way to restrict access to specific warps. For example, I want to make a warp only available to VIPs, but there is no built-in functionality to do this.

Proposed Solution

Introduce a permission node such as eternalcore.warp.vipzone. This permission would allow only players with the specified permission to access the warp (e.g., the "vipzone" warp).

Alternative Solutions Considered

None considered.
