What are Renovate's prHourlyLimit and prConcurrentLimit and how do they work together?

prConcurrentLimit	Maximum total open Renovate PRs at any one time	10
branchConcurrentLimit	Maximum open Renovate branches	Follows prConcurrentLimit

  "prHourlyLimit": 5,
  "prConcurrentLimit": 15,
  "packageRules": [
    {
      "matchUpdateTypes": ["major"],
      "prConcurrentLimit": 2,
      "prPriority": -1
    },
    {
      "matchUpdateTypes": ["patch", "minor"],
      "prPriority": 1
