[eas-cli] Require --environment flag for eas update when SDK >= 55

[douglowder]

Why

Problems can occur if an update intended for a development build is published with the environment defaulting to or set to production, and vice versa.

To prevent such problems in the future, this PR makes the --environment flag a required flag for projects using SDK 55 and greater.

How

Add a new utility function to throw an error if sdkVersion does not meet the requirement, and use that function in eas update:configure and eas update.

Skip the check if EAS_BUILD env is set.

Test Plan

Unit tests added.

Testing locally with different projects.

This is definitely a good change for helping people avoid common pitfalls.

We can't know if there are users currently relying on this flow (reading the values from the local env file). Adding this check would make it impossible. We might need to add an option like --local-environment which would use the local env file as before. But it's ok to add it later if there are actually users who need it.
