Issue

Consider the following recipe:

https://github.com/conda-forge/akamai-feedstock/blob/57bc61b3793785eac37aedf0035ac5b557917253/recipe/meta.yaml#L24-L31

It has a duplicate about.home key. Smithy does not seem to report that:

$ conda smithy recipe-lint recipe --conda-forge
recipe is in fine form

However, it seems to break auto-tick bot (e.g. in https://github.com/regro/cf-scripts/actions/runs/11536519761):

 - We found a problem parsing the recipe for version '1.6.0':
