docs: standardize shell commands in the docs

[richardgreg]

Removed yarn, ensured all examples have two variations and tabularized examples.

close #1459

[arboleya]

Thanks for your contribution!

[richardgreg]

I will make the changes and update the PR.

Is there a command that can build the doc locally?

[arboleya]

You can run the dev command inside the apps/docs dir:

cd apps/docs
pnpm dev

[richardgreg]

I probably should have asked this earlier, should I also change the examples in /packages? And every other instance in the repo?

[danielbate]

@richardgreg Yes please 🙏🏻 This would be beneficial since we only recently started recommending pnpm.

fuels-ts/package.json

Lines 7 to 10 in 17788fe

	"engines": {
	"node": "^18.14.1",
	"pnpm": "^8.9.0"
	},

However, please only change inside packages and leave apps as is (not including your already implemented apps/docs changes). As we may be using yarn/npm for compatibility testing there.
