Draft: chore(package): pnpm up --latest

This brings the effect of pnpm up --latest and resolves unmet peer dependencies of the @astrojs/mdx dev dependency.

 WARN  Issues with peer dependencies found
.
└─┬ @astrojs/mdx 0.19.7
  └─┬ @astrojs/markdown-remark 2.2.1
    └── ✕ unmet peer astro@^2.5.0: found 3.6.0

I didn't know about the --latest flag when performing the Astro 3 upgrade recently.

Consider it a as maintenance hotfix release, tracking our current mainline.

Requires pnpm i after pulling.
