make not dependant on expressive-code

[o-az]

Is your feature request related to a problem?

I have a starlight project that disables expressiveCode. As a result, this package ends up not working and throwing an error

repro:
https://stackblitz.com/edit/withastro-starlight-1npo2c?file=astro.config.mjs

Describe the solution you'd like

Make package fallback to Code from 'astro:components' when expressiveCode is disabled.

I tried patching and replacing the starlight Code component with the Astro one which worked.

https://github.com/HiDeoo/starlight-package-managers/blob/main/packages/starlight-package-managers/PackageManagers.astro#L2-L3

- import { Code, Tabs, TabItem } from '@astrojs/starlight/components'
+ import { Tabs, TabItem } from '@astrojs/starlight/components'
+ import { Code } from 'astro:components'
