doc missing

[sfavazza]

Hello!

Despite reading over and over the official documentation, I had no doubt that tasks.json file was not supported by dap-mode. Though by chance I saw the preLaunchTask keyword in dap-mode.el. Digging a bit more I found out that the tasks.json is indeed supported through the dap-tasks.el, though till today this is what I can read in doc:

Would it be possible to update the documentation, perhaps describing the limitation of such support?

I guess this work should have been related to PR #578

This feature was created by @nbfalcon and I am not quite familiar with the limitations if any.
