Quickstart, installation of forc components

[Braqzen]

Section 2 informs us about forc index but there is no mention of how to install these components. The previous section tells us to install fuelup and then we move into forc index usage.

I believe fuelup does not install forc and any components by default when you first install it.

• If that is true then we ought to add a section into the docs telling users to install some components.
• If that is false then we ought to add a section / comment stating that fuelup will install (probably) the latest components for us so we can move straight into forc index usage without having to worry about installing components ourselves.

@Braqzen

• I believe fuelup automagically installs forc, and forc-index (which is why we didn't elaborate more)
  • The details related to that are here in the Quickstart

@deekerno Could you confirm?

Lmk if I'm misunderstanding something
