Fix dashboard

[javierggt]

Description

The package dashboard generation currently fails. The error in the logs is:

jinja2.exceptions.UndefinedError: 'environ' is undefined

I traced that to the sherpa conda recipe, which includes the following:

  version: {{ environ.get('SHERPA_TAG') }}

and

  run:
    - {{ pin_compatible('numpy') }}

This PR includes changes to handle these, and also a try/except clause to skip the package if there is another jinja error.

I used this branch to manually generate the dashboard.

I also commented out line 247 to verify that the following code does not crash and produces the error message for sherpa:

In [1]: from skare3_tools import packages
   ...: pkgs = packages.get_package_list()
Failed to parse recipe for sherpa: 'pin_compatible' is undefined

This seems reasonable to have the dashboard continue - though I wonder two things:

1. If we should extract lines from the package meta.yaml instead of parsing the whole thing for each package
2. How SHERPA_TAG is getting set in our current build

I just took a few minutes to look into the sherpa build again. I'm not very inclined to fix it, but indeed I must have built it using a SHERPA_TAG environment variable defined.

The sherpa recipe has at least a few other issues (other than the use of the environment):

• ska_builder.py can't be used with this recipe (as noted in its add build recipe for sherpa skare3#1349) and the reason is that it fails the same way as skare3_tools.packages before this PR.
• the target platform is set to osx-arm64 in pkg_defs/sherpa/conda_build_config.yaml
• the path to MacOS SDK is set to /opt/MacOSX11.0.sdk in pkg_defs/sherpa/conda_build_config.yaml. This was OK in the specific case, but in general that will change.

OK, I copied your last comments to a new skare3 general issue just to not lose them.
