This change removes the duplicate values in dependenciesSrc, specifically the '!**/*.mk'.

The getProductionDependencies(root) method returns a list of paths for all production dependencies, excluding test files and all .mk files within those paths. I understand that the dependenciesSrc array only needs one '!**/*.mk', but with the current logic, there would be hundreds of duplicate '!**/*.mk'.

For example:

Assuming productionDependencies is ['dependency1', 'dependency2', 'dependency3']

Before:

dependenciesSrc = [
  'dependency1/**',
  '!dependency1/**/{test,tests}/**',
  '!**/*.mk',
  'dependency2/**',
  '!dependency2/**/{test,tests}/**',
  '!**/*.mk',
  'dependency3/**',
  '!dependency3/**/{test,tests}/**',
  '!**/*.mk',
]

After:

dependenciesSrc = [
  'dependency1/**',
  '!dependency1/**/{test,tests}/**',
  'dependency2/**',
  '!dependency2/**/{test,tests}/**',
  'dependency3/**',
  '!dependency3/**/{test,tests}/**',
  '!**/*.mk',
]
