Change 8-eips.md to 8-supported-specs.md

[Samyoul]

Introduction

8-eips.md currently references both BIPs and EIPs. Granted EIPs are the majority of the specs referenced. However with the inclusion of Vac specs in to this document we would be adding yet another source of specification to the 8-eips.md document.

• Addressing this change is outside the scope of the Waku update PR
• Ok let's update this in a new PR (though an issue probably would be better 😄 )

Proposal

• Add Vac specs into 8-eips.md
• Change name of 8-eips.md to 8-supported-specs.md

Question

• Do we want to add Vac specs to 8-eips.md?
• Do we want to change the name of 8-eips.md to 8-supported-specs.md?

Last call to @status-im/status-core , do you have an opinion on the questions here?

If not no problem, I will proceed with the proposal
