Document how to debug with dap using lunarvim

[Livb-VRC]

When trying out starter.lvim confs I found the debugger weren't working for several of them.

The issue was that I had to install the dap packages through :Mason, however there was no clear way for me to know this or which dap package I should install (for example, for go-ide you're to install delve rather than go-debug-adapter as one might guess based on the name alone)

I think it'd be very helpful to have a page to show how to use dap with lunarvim and furthermore a debug section for each language that says which dap package you should install for that language
