Improve @fuel-ts packages references inside fuels-ts

[luizstacio]

When clicking on from "@fuel-ts/<package>". The link opens the node_modules folder. But it should open the package folder.

PR #238 used the typescript directly, which was good, but pnpm link was broken.
PR #246 fixed the issue with pnpm link, but the correct track of the package was lost opening the node_modules.

We should have both

• Good linking
• pnpm link working

This is another issue I was having since #238. Both linking and clicking refs worked fine before.

I'm actually going to write a script that switches this repo from PNPM+tsup to Yarn+tsc so I can have all the functionality lost with #238 back.

I think we can revert #246. The issue was not being able to link to a Yarn project, but since SwaySwap is also PNPM now maybe that's not an issue?

I'm trying this locally now and it seems fine: #345

(Didn't try linking with SwaySwap though, and I might be breaking other stuff so not sure.)
