Non-numeric colour components reach libvips unchecked

A background object with a non-numeric component such as { r: 'x', g: 0, b: 0 } is parsed into an RGBA array where that channel becomes NaN, which _getBackgroundColourOption returns without checking, so it reaches the native layer and the result is silently wrong rather than rejected. The check sits in this shared helper because every background option (tint, flatten, extend, rotate, create, join, etc.) routes through it, matching the strictness the direct numeric options already apply.

Hello again, thanks for the PR. If we're going to verify colour values then I think we should do so separately for each channel to improve error messaging as received [object Object] of type object doesn't provide enough information for someone to fix the problem.

Good point. I've switched it to validate each channel separately, so a bad component now names the channel, e.g. Expected number for background.blue but received NaN of type number instead of the unhelpful [object Object] message. Test updated to cover a couple of different channels.

##### Upgrade Astro and dependencies

⚠️ **BREAKING CHANGE:** Astro v6 is no longer supported. Make sure you [update Astro](https://docs.astro.build/en/guides/upgrade-to/v7/) and any other official integrations at the same time as updating Starlight:

```sh
npx @&#8203;astrojs/upgrade
```

*Community Starlight plugins and Astro integrations may also need to be manually updated to work with Astro v7. If you encounter any issues, please reach out to the plugin or integration author to see if it is a known issue or if an updated version is being worked on.*

⚠️ **BREAKING CHANGE:** This release drops official support for Chromium-based browsers prior to version 111 (released 07 March 2023) and Safari-based browsers prior to version 16.4 (released 27 March 2023). You can find a list of currently supported browsers and their versions using this [browserslist query](https://browsersl.ist/#q=%3E+0.5%25%2C+not+dead%2C+Chrome+%3E%3D+111%2C+Edge+%3E%3D+111%2C+Firefox+%3E%3D+121%2C+Safari+%3E%3D+16.4%2C+iOS+%3E%3D+16.4%2C+not+op_mini+all).
