Fix nvim-dap not lazy loading (#1216)

* Fix nvim-dap not lazy loading

The keys property had local variables 'dap' and 'dap-ui' that used `require` and prevented all DAP related plugins from lazy-loading.
Fixed this by changing keys to a table and substituting the local variables with a lamba function

* Make debug keybind descriptions more consistent
