* 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
* feat: Set breakpoint icons and their highlight colors
* docs: Delete reference URL (written in PR)
feat: "Break" and "Stop" arguments of vim.api.nvim_set_hl are changed because they are too common nouns
feat: Comment out changes regarding diagnostic symbols so that only those who want to change them can do so
