Update log live template

The `log` live template is set to `Debug.Log($VAR$);` with the `VAR` macro showing basic completion. Expanding this and trying to enter a string literal requires cancelling completion + selection, or hitting `"` will surround `VAR` with quotes. It would probably be better to have the template be `Debug.Log($END$);` or `Debug.Log("$END$");`

Start by locating the `log` live template definition in the ReSharper Unity plugin and inspect how its `VAR` macro is configured. Verify the template's expansion and quoting behavior, then confirm that entering a string literal no longer requires cancelling completion or produces unwanted quotes.
