Support Common Runnables in Run Gutter

[Luka-J9]

FP Frameworks in Scala have their own runnables that are not "App"

examples:
ZIOAppDefault
IOApp.Simple
KyoApp

Similar to #36 this can get unwieldy if it's a long list of custom types

Whatever strategy used to employ there, should likely be used here as well

The best option is to probably query information from Metals, but I am not sure if that's possible. It seems totally seperate from LSP

Yeah as far as I can tell the information is sourced from Tree sitter. Looking at other projects they seem to do what you've already done.

I can try to dig through issues and/or ask the Zed project if there is a mechanism for getting this in another way.

Assuming the scm files are the only way of doing this, and given the relative popularity of zio/cats, maybe it's worth adding anyway?

If not, it might be worth adding a blurb in the readme about this. It wasn't clear to me if I had done something wrong in the runnables script for a little while before digging into this.

Let me know any which way, happy to contribute!

I don't love Zed's approach in this case. but if there is no other way around it then go ahead!

I think I found a related issue already in Zed.
