Update kitty conf
Update kitty conf

- pass more options to pager, such as smart-case search
- add a kitty linenum hint to open vscode

The linenum hint to open vscode is broken because kitty launches
vscode from the working directory of the kitty process, not the
working directory of the shell within kitty.
