⚠️ Slowing down new functions

Warning: Slowing down new functions

As the VueUse audience continues to grow, we have been inundated with an overwhelming number of feature requests and pull requests. As a result, maintaining the project has become increasingly challenging and has stretched our capacity to its limits. As such, in the near future, we may need to slow down our acceptance of new features and prioritize the stability and quality of existing functions. Please note that new features for VueUse may not be accepted at this time. If you have any new ideas, we suggest that you first incorporate them into your own codebase, iterate on them to suit your needs, and assess their generalizability. If you strongly believe that your ideas are beneficial to the community, you may submit a pull request along with your use cases, and we would be happy to review and discuss them. Thank you for your understanding.

This pull request enhances the useClipboard function with permission checks. It uses the usePermission function to query and request the clipboard permission before reading or writing to the clipboard.

• Import usePermission function to check clipboard access (link)
• Declare permissionRead and permissionWrite variables to store the result of usePermission (link)
• Modify updateText function to conditionally call navigator.clipboard.readText based on permissionRead (link)
• Modify copy function to conditionally call navigator.clipboard.writeText based on permissionWrite (link)

@antfu could you please approve the check

You should probably test it goes for the legacy method when the permission is denied
