Release v3.28.1-beta.2 (#2112)

Improvements for Windows users:

• The last modification and last access dates on Windows were not precise enough
  for Cozy Desktop to detect sub-second local modifications. This would
  sometimes lead to Invalid metadata errors when sending modifications to the
  remote Cozy.
  We've increased this precision to include milliseconds so we should not lose
  any local modification anymore.

Improvements for all users:

• Due to a "bug" in Chromium (i.e. which we use through Electron to provide our
  network stack), some error responses sent by the remote Cozy to our file
  upload requests are transformed into a cryptic error which we cannot deal with
  directly. In such cases, we end up interpreting them as unreachable Cozy
  errors which is misleading to you.
  We caught and fixed two of those cases:
  • when sending files larger than the maximum allowed by the remote Cozy (i.e.
    5 GiB for Cozies hosted by us)
  • when the amount of data sent does not match the expected file size (i.e.
    because the actual local file has grown since last we detected a change)

Improvements for macOS users:

• Some steps of the initial scan could be run twice if some local modifications
  were detected while the initial scan was still running.
  We've made sure we don't lose time of consume unnecessary computing resources
  by making sure those steps are only run for the real initial scan.
