Fix Bun Astro init scripts

Generated Astro projects for Bun now use `bunx --bun` for the
`dev` and `build` scripts so Astro runs under Bun instead of
falling back to Node.js.

This updates the `@fedify/init` regression test alongside the
Astro example, package documentation, and changelog so the Bun
workflow stays consistent across generated projects and docs.

+### @fedify/init
+
+ -  Fixed `fedify init -w astro -p bun` generating *package.json* `scripts`
+    that invoked Astro through Node.js.  Bun + Astro projects now use
+    `bunx --bun astro dev` and `bunx --bun astro build`, so the generated
+    development workflow runs on systems that only have Bun installed.

 ### @fedify/next
 
  -  Widened `@fedify/next`'s supported Next.js peer dependency range to
