[Analytics Audit] Podcast view

[danielebogo]

📘 Part of: #2628

This PR adds:
• the missing podcast_screen_podcast_description_tapped event
• the missing podcast_uuid & is_private params to podcast_screen_share_tapped

To test

• Run the app with the trackers log on
• Go to a podcast screen
• tap on the share icon
• confirm podcast_screen_share_tapped is tracked with podcast_uuid & is_private params
• expand and collapse the podcast description
• confirm podcast_screen_podcast_description_tapped is tracked
• Upload a file and upload to the cloud
• In AnalyticsEpisodeHelper add a break point at line 200 and force the status to be uploadFailed
• confirm you see episode_upload_failed tracked with the episode_uuid

Checklist

• I have considered if this change warrants user-facing release notes and have added them to CHANGELOG.md if necessary.
• I have considered adding unit tests for my changes.
• I have updated (or requested that someone edit) the spreadsheet to reflect any new or changed analytics.
