Why

ENG-13525: Update EAS-CLI for new EnvVar features

Update command to use multiple environments, polish the interface.

How

• use variable-name and variable-environment to select the variable
• Use multiselect and multiple environment parameters to allow unlinking multiple envs

All commands that were using name parameter to identify a single variable will use variable-name and variable-environment instead. This change will enable user to distinguish between name and environment that is identifying variable that is acted upon, and name and environment that is a parameter for command.

For example, when the user wants to update variable TEST that has environment production and change its name and change its environment, they can use:

eas env:update --variable-name TEST --variable-environment production --name TEST-update --environment production --environment preview

Test Plan

Added tests
