Add pokemon cries resource field to pokemon endpoint

This is the first pr open for review regarding adding of pokemon cries resource to the api based on #982 and #242

It introduces the field cries to the /pokemon endpoint

"cries": {
    "latest":"https://raw.githubusercontent.com/PokeAPI/cries/main/cries/pokemon/latest/1.ogg",
    "legacy":"https://raw.githubusercontent.com/PokeAPI/cries/main/cries/pokemon/legacy/1.ogg"
}

• latest is the most recent cry of the pokemon and being used in current gen games (source: showdown)
• legacy is the old pokemon cries that were used in roms upto gen5 (source: veekun)

The cries are stored here here

Tests for the above addition can be found here

# cries params
self.assertEqual(
    cries_data["latest"],
    "{}".format(cries_data["latest"]),
)
self.assertEqual(
    cries_data["legacy"],
     "{}".format(cries_data["legacy"]),
)

A PokeAPI/api-data refresh has started. In ~45 minutes the staging branch of PokeAPI/api-data will be pushed with the new generated data.

The staging branch will be deployed in our staging environment and the entire API will be ready to review.

A Pull Request (master<-staging) will be also created at PokeAPI/api-data and assigned to the PokeAPI Core team to be reviewed. If approved and merged new data will soon be available worldwide at pokeapi.co.

The updater script has finished its job and has now opened a Pull Request towards PokeAPI/api-data with the updated data.

The Pull Request can be seen deployed in our staging environment when CircleCI deploy will be finished (check the start time of the last build).
