This PR adds the ability to copy the permalink to a line from within
Zed.
This functionality is available through the `editor: copy permalink to
line` action in the command palette:

Executing this action will create a permalink to the currently selected
line(s) and copy it to the clipboard.
Here is an example line:
```
https://github.com/maxdeviant/auk/blob/56c80e80112744740be1969c89fdd34db4be6f64/src/lib.rs#L25
```
Currently, both GitHub and GitLab are supported.
### Notes and known limitations
- In order to determine where to permalink to, we read the URL of the
`origin` remote in Git. This feature will not work if the `origin`
remote is not present.
- Attempting to permalink to a ref that is not pushed to the origin will
result in the link 404ing.
- Attempting to permalink when Git is in a dirty state may not generate
the right link.
- For instance, modifying a file (e.g., adding new lines) and grabbing a
permalink to it will result in incorrect line numbers.
Release Notes:
- Added the ability to copy a permalink to a line
([#6777](https://github.com/zed-industries/zed/issues/6777)).
- Available via the `editor: copy permalink to line` action in the
command palette.
