conditionNames defaults to `["node"]` according to docs, but possibly doesn't actually

[43081j]

the readme specifies:

enhanced-resolve/README.md

Line 86 in 651e578

| conditionNames | ["node"] | A list of exports field condition names |

however:

enhanced-resolve/lib/ResolverFactory.js

Line 194 in 651e578

conditionNames: new Set(options.conditionNames),

seems here we don't actually default the condition names array to anything, so later on the various plugins receive and empty set.

should it possibly be this instead:

conditionNames: new Set(options.conditionNames || ['node']),

@43081j Yeah, I think we should to fix a docs, because change it in the current version will be a breaking change
