Update DataLab's DRAGONS to v3.2.1

[bmerino95]

A new version of DRAGONS was released last week, which includes some updates to the documentation and speeds up the wavelength calibration process.

I would like to request that the DataLab update to this version of DRAGONS. This request is not a high priority since the changes are not dramatically different from the previous release.

I have tested all the DRAGONS notebooks using the newly released version and found that they all run without any new errors or warnings.

A warning on the DRAGONS release notes page says this version is incompatible with numpy v2.0 and higher. That should be fine since DataLab is currently running numpy v1.26.1, but I wanted to document this in case it becomes relevant later.
