#8273: Fix App crashing when chrome runtime is undefined

[johnnymetz]

What does this PR do?

• Closes App crashes on latest Extension version because chrome.runtime is undefined #8273

Discussion

• Instead of using optional chaining we could use isExtensionContext(). But @grahamlangford and I decided to use optional chaining because it's simpler. Plus we will delete the src/mv3/api.ts file when the MV3 transition is complete so no need to create a robust solution here.

Future Work

• Bump Extension version in App. Will need to go from 1.8.11 -> 1.8.13

Checklist

• Designate a primary reviewer: @grahamlangford
