fix(docs): corrected errors in installation instructions

[vsu727]

Fixes issue #2086

Motivation

Due to errors or outdated information in the Farcaster Hub installation guides, the Hub cannot be synchronized due to lack of memory which will prevent it from starting and working correctly. This error is very important because it creates difficulties for new users at the very initial stage of work and familiarization with Farcaster Hub

Change Summary

Changes have been made regarding the minimum amount of memory required for Farcaster Hub to work correctly. The old value is 60 GB in the GCP installation guide and 140 GB is the old value in the main installation guide. Farcaster Hub currently takes up about 150 GB. The old memory values have been changed to 160 GB, which allows you to run the Hub and have a reserve of correct operation for a period of time

Additional Context

According to the GCP guide we create a virtual server and set the server parameters via Google Cloud Console by copying the data from the guide into the created file "main.tf"

The virtual server has been configured with these memory settings

Then after running the script specified in the main installation guide on the created server Hub starts synchronization, but after a while it stops with the error "code 2".

This error means that Hub cannot continue synchronization due to lack of memory
