use latest chainsim

[bogdan-rosianu]

Reasoning

• Previously, we had to use a custom tag for chainsimulator that included all the fixes we needed for e2e tests
• But latest chainsimulator release already includes all the fixes

Proposed Changes

• set latest version of chainsimulator

How to test

• E2E chain simulator tests should pass
