A problem during installing OGGM using the yml file

[Keeptg]

Hello! I'm not sure if this is a widespread problem, so I report it here just in case.
I encountered an error (see the detailed error in the end) during create an oggm environment by using the yml file in mamba.
While when I add - python=3.9 in the dependencies , the OGGM environment will be created successfully.

The error I encountered is as following:

Pip subprocess error:
  Running command git clone --filter=blob:none --quiet https://github.com/OGGM/pytest-mpl /tmp/pip-req-build-9fec9bdl
  fatal: unable to access 'https://github.com/OGGM/pytest-mpl/': gnutls_handshake() failed: The TLS connection was non-properly terminated.
  error: subprocess-exited-with-error
  
  × git clone --filter=blob:none --quiet https://github.com/OGGM/pytest-mpl /tmp/pip-req-build-9fec9bdl did not run successfully.
  │ exit code: 128
  ╰─> See above for output.
  
  note: This error originates from a subprocess, and is likely not a problem with pip.

Let's address this as part of the "Install OGGM documentation" overhaul.
