feat: add system.cron

[nhammond101]

Adds new functionality to generate cron expressions.

New Function:

• faker.system.cron()

Usage:

faker.system.cron():

// generates a random cron expression
console.log(faker.system.cron()): // '45 23 * * 6'

supports an optional options object, which currently has a year component

// generates a random cron expression with a year
console.log(faker.system.cron()): // '45 23 * * 6 2067'

Unit tests for the functions added.

Targeting it for v6.3, but I don't think it will make it so fast We plan to work on v7 in next "sprint"

[ST-DDT]

Should we add some range for the cron: E.g. yearly, daily, ... (nothing precise, just some generaly direction)

[nhammond101]

Should we also try to generate some more advanced cron strings like 23 0-20/2 * * *?

i'd like to, I wanted to get the simplest expressions generated first and potentially gauge demand

@nhammond101 Could you please update this PR?

[ST-DDT]

Please rebase your commits/PR:

git fetch --all
git rebase origin/main
git push -f

(assuming origin is the main faker repository)

Alternatively, we can do that for you, but then you have to reset your local checkout.

@Shinigami92 if you get a few minutes, would you post your approach?
