It's not possible to configure the BASE_URL for a domain starting with board

Describe the Bug

It's not possible to configure the BASE_URL for a domain starting with board, becouse https://board.myproject.com contains /board and the function checkBaseUrl of file run.js do this:

 function checkBaseUrl() {

    const baseUrl = process.env.BASE_URL;

    if (baseUrl) {
      if (baseUrl.includes('/board')) {
        return error('env.BASE_URL must point to the root of the webapp');
      }

I think that you can change the code to first check if the baseUrl format is not valid, then check why, somethink like this:

 function checkBaseUrl() {

    const baseUrl = process.env.BASE_URL;

    if (baseUrl && !baseUrl.match(/^https?:\/\/(\.?\w+)+$/)) {
      if (baseUrl.includes('/board')) {
        return error('env.BASE_URL must point to the root of the webapp');
      }

Steps to Reproduce

try to configure the BASE_URL for a domain starting with board

Environment

• Host (Browser/Node version), if applicable: [e.g. MS Edge 18, Chrome 69, Node 10 LTS]
• OS: [e.g. Windows 7]
• Board version: [e.g. 1.0.0]

Good catch. I think the check can be further simplified. It should basically prevent users from setting {TASK_BOARD}/board as the BASE_URL over {TASK_BOARD}.
