Sprint 27: April 29 - May 12

A smaller release for this one because we're also gearing up for a mid-sprint feature-release, look out for that in the next few days!

• Upgraded Typescript from 3.7 to 3.8, which required updating Prettier from 1.x to 2.0.5. This impacted a large number of files at a cosmetic level but did not result in any functional changes
• Improved user agent detection for recording on Safari
• Removed the legacy Nubis configuration files
• Sentences and localization updates
  • Renamed hi-IN to hi after discussion with the community
  • Incorporated corpus extracted from Dutch Europarl transcriptions
  • Added Odia as a contributable language
• Minor UI bugfixes
