[eas-cli] Support requireCommit for EAS Update

[wschurman]

Why

When the requireCommit preference has been set in eas.json (cli section), the eas update command should read and respect that preference.

Closes ENG-11110.

How

Apply same function calls as build/submit.

Test Plan

1. Add requireCommit: true to eas.json cli section

$ neas update
