Add AmSC Python client to dashboard environment

[EZoni]

Overview

Follow up on #455 and extracted from #439, with the caveat that we now install the latest main version of the client.

Taken from the README in https://gitlab.com/amsc2/infrastructure-and-services/amsc-interfaces/amsc-python-client.

Note that this doesn't have the @ file:///home/edoardo/src/amsc-python-client workaround included in #439, as we should be able to move forward with the main branch of the AmSC Python client now.

I removed the [globus] for now, since it does not seem to pull in any dependency in the resulting lock file. I will test again as I start merging features specific to the AmSC IRI API and update in separate PRs, if needed.

I merged main as is in 860c297, without changes, but also recreated the lock file from scratch in 236ee75 to be sure I didn't mess anything up. Packages and dependencies change on a daily basis, so there are now a few additional updates beyond the AmSC Python client, even if the previous update was less than 24 hours ago.
