Update build.scrt.network

[cankisagun]

Update https://build.scrt.network/ content / go over all the tabs to looks for:

• working links (if they point to the right place. For example last week I just changed rocketchat links to discord)
• informational inconsistencies (like talking about secret contracts don't exist yet and we are using CosmWasm)
• potentially missing information that you'd like to see

You can skip developers - > quick start guide. We are working on this repo separately

• Index - https://github.com/enigmampc/SecretNetwork/blob/master/docs/.vuepress/config.js
• Docs - https://github.com/enigmampc/SecretNetwork/tree/master/docs
