BookFaker could try to resolve "#{Name.name}" in one of its functions,
which would try to lookup the `Name` provider that isn't available
in the BooksFaker.

In such cases we try to find the `Name` provider in the core `Faker`
implementation, and failing that thrown an exception to make the
error clearer.

We do not try to support CustomFaker -> AnotherCustomFaker calls,
e.g. BooksFaker -> MusicFaker.
Only CustomFaker -> Faker is supported, i.e. BooksFaker -> Faker.

Also make safer some provider implementations that utilize secondaryCategory
by allowing `YmlFakeDataProvider#resolve` to take Category as parameter instead of String

Use this to move all files with GAMES category:

grep -lRF 'override val yamlCategory = YamlCategory.GAMES' \
  core/src/main/kotlin/io/github/serpro69/kfaker/provider/ | \
  xargs -I {} mv {} provider/games/src/main/kotlin/io/github/serpro69/kfaker/games/provider/

Then move a couple more, which have their own primary category,
manually.

This included moving test files also, so had to add a
testImplementation dependency on 'core' to the
faker-provider-conventions plugin.

Integration tests were also failing, particularly those that are
used in docs, so needed to add some integrationImplementation
dependencies on a new module also.

Apparently they've started using Anchors and Aliases in yml files
upstream (see e.g. uk.yml -> male_first_name -> first_name).

Seems like jackson can't handle Anchors properly
(see FasterXML/jackson-dataformats-text#98)

As a workaround, we use snakeyaml to read .yml files to Map objects,
and then we use jackson to write them to .json files, since snakeyaml
seems to support anchors just fine without needing to jump through hoops.

Room and TheRoom have the same data/functions

This leaves the core Faker with only its own data generators.

Keep plurality consistent across fakers' names
