feat: Add configurable closing keymap

- Added `floating_buffer_exit_keys` in `config` which contains keys to close floating buffer.
- Modified `close` attribute in `toggle_saved_queries` function to use keys from `config.floating_buffer_exit_keys`.
- Implemented `set_config` function in `ui.lua` to update the configuration options.
- Changed attribute `enter` in `trigger_hover` function from `false` to `true`.
- Restructured `trigger_hover` function to use keys from `config.close_floating_buffer` for closing the buffer.
