wezterm: Add url-opening to quickselect

Added new quickselect mode to quickly open a displayed url. Changed
original quickselect to use leader-f mapping (instead of shift+f) and
made new mode callable through the shift+f version.

from: https://github.com/wez/wezterm/issues/1362

Delegated scroll mode invocation to leader-b, as in original setup.
