<sl-icon> Iconoir documentation example broken after Iconoir v7 update

Since Iconoir v7.0.0, the CDN path for icons changed, causing the Shoelace documentation example for the Iconoir library to break.

• Old path:
  https://cdn.jsdelivr.net/gh/lucaburgio/iconoir@latest/icons/${name}.svg
• New path:
  https://cdn.jsdelivr.net/gh/lucaburgio/iconoir@latest/icons/regular/${name}.svg

To Reproduce

Steps to reproduce:

1. Visit Shoelace Icon Component — Iconoir example
2. Observe that the icon does not load

Expected behavior

The example should load the Iconoir icons using the updated CDN path.

Suggested fix

1. Update the CDN path in the documentation example to the new format.
2. Update the example icon reference:
   xml复制

   <!-- Current (invalid) -->
   <sl-icon library="iconoir" name="check-circled-outline"></sl-icon>
   
   <!-- Suggested -->
   <sl-icon library="iconoir" name="check-circle"></sl-icon>

Note: check-circled-outline no longer exists in Iconoir v7.
