 `$is_edge` is `true` when "Edge" is detected.

 However, user agents for Edge have changed such that "Edg" is the only
 consistent substring across devices. As a result, `$is_edge` returns

 Changing the substring to "Edg" in `src/wp-includes/vars.php:68` seems to
 fix this.

 Steps to reproduce and test the solution:
 1. Add this to `functions.php`:

 global $is_edge;
 die( var_export( $is_edge, true ) );

 2. Load any page. `false` should be displayed.
 3. Change "Edge" to "Edg" in `src/wp-includes/vars.php:68`.
 4. Reload the page. `true` should now be displayed.
