Update tests workflow from conda/conda

[jaimergp]

I noticed there were some outdated parts in the workflow (e.g. truststore, linux-aarch64 support) so it was time to refresh it.

Since we are only testing one Python version (3.10) to keep thing light in this still in-progress repo, I changed the matrix configuration to include because it's way clearer when we have so few cases.

I also:

• removed the qemu and benchmark tests for now, since they were disabled. If we ever want to add them back, it'll be a matter of copying the blocks as needed.
• removed tests/test_workarounds.py, since they don't apply for rattler (more details in commit message)
• added a temporary workaround for Translate POSIX set to xonsh's equivalent setup-miniconda#442 doesn't work, will fix in a different PR

Did the workaround not work around?

Did the workaround not work around?

Some weird interactive vs non interactive code. I guess the fake shell for the tests passes as interactive when it's not really one, so some of the assumptions in xonsh fail:

Warning: Input is not a terminal (fd=0).
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/xonsh/main.py", line 469, in main

/bin/bash: line 1: `__xonsh__.execer.exec($("/usr/share/miniconda/envs/test/bin/python" -m conda shell.xonsh hook))'

I tried using an env var to disable the welcome message which is apparently involved in this terminal size query, so we'll see. If this doesn't work, I'll just wait for the new setup-miniconda release (tomorrow, I guess).

Ugh, setup-miniconda it is then. Can you take a look when you have the chance, @jezdez? Thanks!

conda-incubator/setup-miniconda#443

[jaimergp]

I'll merge for now, since any updates will need a bump in setup-miniconda anyway.

@jaimergp Released the setup-miniconda update

Let's see if #34 works!
