[inoas]

Allow setting erlang/beam, deno or nodejs boot args.

@JohnBjrk I used it to pass --perf flag to node which was quite useful for understanding my performance bottleneck on map inserts. https://discord.com/channels/768594524158427167/768594524158427170/1084496932195549184

I think it would be useful if this feature also supported using ts-node to run node code, ie node ts-node gleam_module.mjs

Super useful, especially on the BEAM. We'll need to figure out a good design for this so let's start by researching what other languages do here.

I though we had an existing issue for this but I can't find it now 🤔

just a list of args then maybe? like so:

[javascript.node]
startup_arguments = ["ts-node"]

We need to do research and see what other languages and build tools do.

This is not runtime configuration so I think it is out of scope here.
