Subject: [PATCH] ci: expose python version for translate tests

With NDSL supporting more than one version of python, we'd like to have
the possibility to run pyFV3 translate tests with different versions of
python. This PR adds an optional input variable to the `workflow_call`
which allows calling workflows to specify the python version.

The PR also removes usage of the `component_trigger` input variable. The
input is redundant with `component_name`, which is a non-empty string
whenever `component_trigger` is true. I keep the input around until we
update all calling workflows to not set it anymore.
