Replace usage of arrays when there is a single item in the dependency list

[yeikel]

What problem are you trying to solve?

Improve readability of the workflow

What precondition(s) should be checked before applying this recipe?

There is one single item within the needs block and an array is used

The recipe should not be applied if there are multiple entries

  docker-build:
    needs: [ maven, slack ]
    uses: ...

Describe the situation before applying the recipe

  docker-build:
    needs: [ maven ]
    uses: ...

Describe the situation after applying the recipe

  docker-build:
    needs: maven
    uses: ...

Did you mean to expect needs: maven in your after block?

My bad, obvious typo. I updated it :)

[yeikel]

@timtebeek This pattern is also present in other blocks. For example

on:
   types: [ labeled ]

Should that be a separate recipe?

Same question for #129

No I'm thinking we can make that a recipe that just takes a JsonPath as argument, and applies the same logic as described above.

Perhaps split this into two, one that works via JsonPath, and another that reads it automatically? Having less arguments to pass would be better, in particular in builds with many jobs/variable names in an organization :)
