Configure Vite to use HTTPS when HTTPS is enabled

Overview

Configure Vite to use HTTPS when HTTPS is enabled.

When Vite is running without HTTP/2, it's extremely slow and it can crash HTTP router due to exceeded number of concurrent requests:

• #2179 (closed)
• gitlab#423851

This is the smallest iteration to make Vite performant and also compatible with HTTP router. This also requires gitlab!182264 (merged)

An alternative bigger proposal using Nginx can be found at: #2382

This issue was spun off from #2382 (comment 2360497496)

Current workflow

graph LR
  subgraph cell2
    direction LR
    workhorse2 --> rails2
    rails2 --> vite2
  end

  subgraph cell1
    direction LR
    workhorse1 --> rails1
    rails1 --> vite1
  end

  browser --> http-router
  http-router --> workhorse1
  http-router --> workhorse2

Updated workflow

graph LR
  subgraph cell2
    direction LR
    workhorse2 --> rails2
    vite2
  end

  subgraph cell1
    direction LR
    workhorse1 --> rails1
    vite1
  end

  browser --> vite1
  browser --> vite2
  browser --> http-router
  http-router --> workhorse1
  http-router --> workhorse2
