[Bug]: copied channel link is a local url that can't be shared

Guidelines

• [X] I have encountered this bug in the latest release of FreeTube.
• [X] I have searched the issue tracker for a bug report that matches the one I want to file, without success.
• [X] I have searched the documentation for information that matches the description of the bug I want to file, without success.

Describe the bug

1. Go to any page that has at least one video
2. Right click on the channel name/link
3. Click the Copy Link item
4. Paste to any other places
5. Got a not sharable link like: file:///opt/FreeTube/resources/app.asar/dist/index.html#/channel/xxxxxx

Expected Behavior

Copy the link with proper prefix, instead of file:///opt/FreeTube/resources/app.asar/dist/index.html#, it should be https://www.youtube.com/.

Or even better, the behavior on Youtube.com, that link will be with customized string, which is something more readable. For example, instead of https://www.youtube.com/channel/UCSJ4gkVC6NrvII8umztf0Ow, it'll be https://www.youtube.com/c/LofiGirl
