feat: add versions description command for ios and android

[adamfilipow92]

Fixes #975

Test Plan

How do we know the code works?

When run

flank firebase test android|ios versions describe VERSION_ID

flank should return output like gcloud cli when execute

gcloud alpha firebase test android|ios versions describe VERSION_ID

example for flank firebase test android versions describe 28

apiLevel: 28
codeName: Pie
id: '28'
releaseDate:
  day: 6
  month: 8
  year: 2018
versionString: 9.x

example for flank firebase test ios versions describe 11.2

id: '11.2'
majorVersion: 11
minorVersion: 2
supportedXcodeVersionIds:
- 10.2.1
- 10.3
- 11.0
- 11.1
- 11.2.1
- 11.3.1
tags:
- default

example for the wrong VERSION_ID flank firebase test android versions describe test

ERROR: 'test' is not a valid OS version

Additional informations

Some supportedXcodeVersionIds is returned in single quotes on describe command like:

id: '11.2'
majorVersion: 11
minorVersion: 2
supportedXcodeVersionIds:
- 10.2.1
- '10.3'
- '11.0'
- '11.1'
- 11.2.1
- 11.3.1
tags:
- default

Api returns all versions without quotes so I cannot determine what version should in quotes. I asked on test-lab slack to get more info.

Checklist

• Unit tested
• release_notes.md updated

For incorrect version, gcloud ends run with exit code 1 where flank's s 0. I think we should also reflect this.
