import and call the env analysis script (#4)

* import the script

* list the dependencies

* call the script from within the action

* explicitly specify the shell

* quote the `envs-path` variable

* try setting the input type of env-paths

* try serializing to json

* quote the input

* missing shell

* correct the input name

* print the decoded paths

* typo

* use the right function names

* unquote

* try using `join`

* remove debug step

* allow expected failures

* add test env files

* compare strings instead

* pass expected failure as a list

* another failing example

* show the status of the current dir

* more debugging

* print the content of `envs`

* rename `env1`

* use a existing version of `pandas`

* use an existing version of `packaging`

* enforce a column width of 120

* proper syntax

* try setting in a different place

* remove debug step

* enforce colors

* remove the `always`

* split up into smaller steps

* don't cancel in-progress jobs when others fail

* cancel duplicate workflow runs

* continue if the action fails

* more output

* tests for `Spec.parse`

* always set the pass status

* check the output of the status functions

* consolidate into a single step

* continue on error

* some more adjustments

* fix the `xfail`

* Apply suggestions from code review
