Improve faker.finance.accountName localization

[matsueushi]

Clear and concise description of the problem

The faker.finance.accountName() method currently returns account names with a hardcoded 'Account' suffix in English:

fakerJA.finance.accountName(); // '当座預金 Account'

Suggested solution

The suffix should be customizable to match the context and language of the active locale. For example:

fakerJA.finance.accountName(); // '当座預金口座'
