Use special Expo SDK runtime version for managed projects

[wschurman]

Why

This PR adds support for a special runtime version indicating that the runtime is an expo SDK preset runtime (SDK version). With this special runtime version the user will be able to load the app in Expo Go (as long as expo go has that runtime version). Otherwise the user will need to use the dev client to develop their app.

From https://github.com/expo/universe/pull/7299:

• In eas-cli (this PR) publish default to the runtimeVersion returned from getRuntimeVersionForSDKVersion when one isn't supplied and the project is managed.
• In native code, parse this runtime version to extract the sdk version. [updates] Add support for loading new manifests in Expo Go expo#12521
• In home query for EAS updates and parse their runtime versions. If a runtime version is this special format, allow it to be launched in Expo Go with the parsed SDK version. If not, tell the user that a custom client build (dev client) must be used to run the project. [updates] Add EAS updates to Expo Go project page expo#12525

How

Add code to default the runtimeVersion to the SDK version if in managed and the runtime version is not specified.

Test Plan

In a managed project without runtimeVersion specified:

> /Users/wschurman/expo/eas-cli/node_modules/.bin/eas branch:publish main
✔ Generating runtime version from sdk version
✔ Linked to project @wschurman/watwat
✔ Building bundle with expo-cli...
...
✔ Uploaded assets!
✔ Please enter a publication message. … woo2
✔ Published!
