feature: optional task/debug parameter for :LaunchTask and :LaunchDebugger

[costowell]

Did you check the documentation and existing issues?

• I have read all the launch.nvim documentation
• I have searched through all existing issues of launch.nvim

Is your feature request related to a problem? Please describe.

This plugin is just fantastic. All I want is the ability to map some keys to a few common task names like Build or Run.

Describe the solution you'd like

I think the best way to do this is to take an optional parameter like the title says.

Describe alternatives you've considered

At the very least, it'd be nice to expose a nice lua api because, at the moment, I need to copy a lot of code to do what I want.

Additional context

Thank you for your time.

I would be happy to make a PR if that is preferable.
