feat: add copy readme as markdown button on package page

[carwack]

This should solve: #1020

I did implement it the way I understood it and took my inspiration from the Ark UI docs.
This PR adds a new copy README as markdown button for the README on a package page. This makes it possible to have the README content as markdown in the users clipboard.

I have also added the translations for the following languages:

• EN
• fr-FR
• de-DE
• es
• it-IT

Capitalise “Markdown” in the label.
Minor copy consistency for a proper noun.

✏️ Proposed copy tweak

-      "copy_as_markdown": "Copy README as markdown"
+      "copy_as_markdown": "Copy README as Markdown"

🧹 Nitpick comments (2)

server/utils/readme.ts (1)

272-272: Consider making raw markdown lazy to avoid payload bloat.
Shipping both HTML and raw Markdown can nearly double response size for large READMEs. If this becomes a performance concern, consider fetching md on demand (or behind a flag) instead of always returning it.

Also applies to: 456-459

app/pages/package/[...package].vue (1)

1139-1172: Clean implementation of the copy button UI.

The button is correctly guarded by v-if="readmeData?.md" and integrates well alongside the existing TOC dropdown. Accessibility attributes are properly applied.

Two minor observations:

1. Redundant disabled attribute (Line 1149): Since the parent TooltipApp already has v-if="readmeData?.md", the button only renders when md is truthy, making :disabled="!readmeData?.md" always evaluate to false. Consider removing it or keeping it for defensive coding if the structure might change.

2. Overlapping CSS classes (Lines 1150-1153): The static class includes text-fg-subtle hover:text-fg, which duplicates the dynamic :class binding for the non-copied state. This is harmless but could be tidied up.

♻️ Optional: Remove redundant disabled and consolidate classes

               <button
                 type="button"
                 `@click`="copyReadme()"
-                :disabled="!readmeData?.md"
-                class="px-2 py-1.5 font-mono text-xs rounded transition-colors duration-150 text-fg-subtle hover:text-fg inline-flex items-center gap-1.5"
-                :class="
-                  copiedReadme ? 'text-accent bg-accent/10' : 'text-fg-subtle bg-bg hover:text-fg'
-                "
+                class="px-2 py-1.5 font-mono text-xs rounded transition-colors duration-150 inline-flex items-center gap-1.5"
+                :class="copiedReadme ? 'text-accent bg-accent/10' : 'text-fg-subtle bg-bg hover:text-fg'"
                 :aria-label="
                   copiedReadme ? $t('common.copied') : $t('package.readme.copy_as_markdown')
                 "

Based on learnings: The copy button pattern in this file is acceptable inline with the CSS-only approach for smooth animations; a reusable component may be introduced in the future.

love it! I think your PR title needs casing correctly, I unfortunately don't have such powers

[carwack]

@ghostdevv happy to hear that! Yes I forgot a space I think but I can't edit the title 😅
