headerGenerator behaves differently than expected for safari browser

[kashif-ghafoor]

Describe the bug

headerGenerator

1. throws error for browserListQuery "last n safari version" where n is any number
2. if I set minVersion to 18 it produces headers for safari browser version lower than 18 even with strict property set to true

To Reproduce

case 1

// will produce "No headers based on this input can be generated" error
const generator = new HeaderGenerator({
  browserListQuery: "last 10 safari version",
  operatingSystems: ["macos"],
  devices: ["desktop"],
});

case 2

// will produce headers for browser version lower than 18
const generator = new HeaderGenerator({
  browsers: [
    {
      name: "safari",
      minVersion: 18,
    },
  ],
  operatingSystems: ["macos"],
  devices: ["desktop"],
  strict: true,
});

Expected behavior
for case 1 we expect the generator to generate headers
for case 2 we expect it to produce headers with safari version >= 18

System information:

• OS: MacOS
• Node.js version 22
• header-generator version 2.1.61
