Fix checksum for 2.1.0

[M3R14M]

Problem

• Error while trying to upgrade to version 2.1.0:

  YunoHost was able to download the asset 'main' (https://github.com/penpot/penpot/archive/refs/tags/2.1.0.tar.gz)
  for penpot, but the asset doesn't match the expected checksum. This could mean
  that some temporary network failure happened on your server, OR the asset was
  somehow changed by the upstream maintainer (or a malicious actor?) and YunoHost
  packagers need to investigate and perhaps update the app manifest to take this
  change into account.
  
    Expected sha256 checksum: b3e0f9816e838e2ce12e29cbe13af5efa2756d4a8f66111adfce28bc6d4391b7
    Downloaded sha256 checksum: 47b816b92896c0786196385150fb4a8c7e5d3240516f7d48da1c998910f5c006
    Downloaded file size: 56M

Solution

• Matched the checksum to downloaded assets
