Consider reducing priority of credit card validator warning

[mkoniecz]

What steps will reproduce the problem?

1. Create node
2. Add payment:credit_cards=yes
3. Run validator

What is the expected result?

No complaints

What happens instead?

payment:credit_cards=yes is inaccurate. Use separate tags for each specific type, e.g. payment:mastercard=yes or payment:visa=yes. (1)

Please provide any additional information below. Attach a screenshot if possible.

At least in Poland spending time on providing more specific info would be complete waste of time. Anything supporting credit cards will support mastercard and visa duopoly, there is basically no use of other credit cards.

This warning really should be at info level.

For additional context: I considered implementing StreetComplete quest collecting this info (like I did for some other missing values, AFAIK some inspired by JOSM validator warnings). But I decided that it would be waste of time - both for developing and both for collecting data. At least in areas known to me.
