fix(accordion): remove unintended clipboard copy on open

[20syldev]

Summary

Fixes #27 (reported on mintlify/mdx#27).

Clicking an accordion to expand/collapse it was silently overwriting the user's clipboard with the current URL + hash fragment. This behavior was unexpected and disruptive — especially when the user had something else copied.

• Removed the copyToClipboard(newUrl) call in updateAndCopy
• Removed the now-unused copyToClipboard import
• The URL hash is still updated via window.history.replaceState so deep-linking to open accordions continues to work

---

Note

Low Risk
Removes an unintended clipboard write during accordion URL management; behavior change is limited to client-side UX and should not affect data or security.

Overview
Accordion URL management no longer copies the generated deep-link URL into the user’s clipboard when sections are opened/closed.

The unused copyToClipboard import is removed, and URL updates continue to happen via window.history.replaceState so hash-based deep linking still works.
